That's a very good question and one I've asked myself at various times since becoming self-employed. It happened for me in my early 30s (just over 10 years ago), so you have a strong head start. I didn't have access to forums like RVF and the wealth of opportunities for self-publishing, tools for marketing to / connecting with customers. I'll share some my experience, tools I've found useful, and general attitudes.
I was also very blue pilled until getting laid off (during early 2000s tech bubble bursting). That was a big wake up call. I hated not being in control of having income, and answering to a boss who turned out to be a slave driving asshole sociopath (with a Master's degree).
I love being creative. I love coming up with solutions to existing problems, and seeing opportunities for advancing my field / areas of interest. I love finding information and situations that relate to each other - you can't do that when you're plugged into someone else's time frame. Obviously being self-employed you often have a lot of work or no clear ability to leave work at the office (especially if you work at home). Creating some kind of rhythm / schedule is really important so you can both stay on top of customer demands / projects and also make time for yourself and your creative process.
Very happily, I will go to the beach, take a hike, get a massage during the day when the W-2/9-5ers are working. I allow myself to work when needed and also make space for inspiration to arise. It doesn't always happen at a set time so being flexible is very important. I'm naturally an idealist, a dreamer, and also pragmatic about taking care of business needs. By managing the details that make your business operate and keep your customers happy (including not over-promising on deadlines / timelines!), I carve space in my daily rhythm for insight and inspiration. An entrepreneur - in the truest sense - is a visionary. You are not just bringing a new service, but a new outlook on what you're doing, how you're doing it.
In my case, I've had to take an industry that is loaded with engineers and engineering jargon and come at it from a physics perspective (first-principles, what works, how to optimize). It's been working very well and I'm well-respected in my contributions. I also love to share information, ideas, perspectives via Youtube videos and blog posts. They're not professionally created which may be a detriment, but I also am a procrastinator so focusing on making it look pretty would distract me from just getting it out there and I focus on quality content (and quality results) not high production value. You might find more value in the opposite - creating resources / videos / presentations that appeal to the high-end financial market. Being a lone wolf in the business world you can and (IMO) need to leverage your knowledge, perspective, and uniqueness to set yourself apart from anyone else in your field. I don't care how that looks, you just need to do it. Or not, but if I hadn't differentiated myself I would be just another vendor in an already crowded field. Because I took the time to really understand WHY I am into this - not just to make money or because I'm good at it, but WHY it drives me to study, understand, improve - I have an honest passion that people can see, hear, and feel. I KNOW why they need to work with me not any other company (including those who are multi-million dollar).
You mentioned the tendency for immediate gratification - that's not just a pejorative unfairly applied to Millenials (though I've seen many it applies to) it applies to many people in our society, including older generations. This is why I have made myself more focused on one-on-one interactions via phone or in-person rather than email / text. I make it a point to talk on the phone with all my customers, including those overseas. I want to get to know them a little bit, create a personal connection. It also helps me understand how to optimize my products and services for their needs. The personal touch as impressed upon me at an early age, something my Dad did when he rented our vacation house and met each renter at the local Denny's. He made himself very available so after about 5 years he never needed to advertise, referrals kept coming in and repeat business. Your business may be different, but asking for referrals, networking and getting qualified leads is exceptionally important. Learning to slow yourself down is essential; meditation, yoga, tools for cardiac coherence / breath work like Institute of HeartMath, light box therapy (kudos Lizard of Oz!), optimal nutrition. I also really love following the change of seasons and feel the calming and grounding rhythm of life. Most people stuck indoors don't feel the seasons change from week to week and month to month. You feel more tapped in to Life and Nature when you can have windows or doors open, or at least be outside during the day (if not in a blizzard). The mind wants to get everything done NOW, the body knows it all takes time. It's also important to not rush people either; that sucks. A fast-paced life is a recipe for a disaster so whatever you can do in grounding yourself will pay dividends.
I would watch the TED talk 'How Great Leaders Inspire Action' by Simon Sinek, read my post on finding your purpose
thread-59636.html (the Richard's book is worth its weight in gold!), and watch some Gary Vaynerchuk
https://www.youtube.com/watch?v=zADf21b28BY. Randy Pausch (RIP) has some great videos on Time Management and his 'How to Achieve your Childhood Dreams / Last Lecture' talk is also inspiring. I've benefited from coaching with Maui Masterminds (did one year, their discussion on Time Mastery was probably my favorite part - learning how to really value your time, be clear on what activities you do create the most value, and delegate / out-source / eliminate the activities that don't create value or revenue).
I am not yet making as much as I want to, but last year was a turning point. I am an expert in what I'm doing, and I LOVE what I'm doing. I charge more for what I do, have fewer and better quality customers, and more time to invent, innovate, create, rest well, eat well, exercise hard, play hard, and enjoy my life. The clearer I get on who I am and what gifts separate me from everyone else, the more confidence I have. I also need to give back (like engaging on this forum or in real life with people who can benefit from what I've learned) because I've had so much help on this journey. I have some new connections that are going to open up incredible revenue opportunities. It's taken 10 years for this to happen but I fiddle-farted around for a couple years before getting really serious.
You may be right that in the short term the traditional route would give more benefits in the financial realm - I've had some sacrifice there as well - but thinking short terms leads to slavery. I'm sure people can be happy enough working for someone else, but that isn't me. I've got big goals and clear plans on how to execute them. No one else will ever care as much about my passions and dreams as me. You can't transfer your passion and insights to someone else - you can inspire others, but they will always be their own person.
I guess one way to look at it is - can you see some way for your field to be improved, in a way that you can help make that happen? What's the missing piece the other firms aren't getting, or aren't doing as well as you are, or as well as you can? Are they using the best tools, the best research, the best communication methods, the best feedback loops? What in the system or process could be better, and can you be the person who makes that happen? Can you imagine or inventor and patent / license better methods than currently exist? I didn't know for about 3-4 years of total dedication to my craft that I could find something no one had seen or fully articulated, but I have now. In fact, it led to connections I didn't expect in other areas. I really don't believe one subject is totally disconnected from another; everything is really connected. The more you explore, read, study, connect and talk with people to learn not just pick-up, the more you see how what you do fits into the broader world. You have to be willing to be both very alone / solitary and also very engaged. That's what I've found and I think a lot of the most successful people fit this profile - Trump certainly loves his alone time and Melania understands this about him.
You didn't mention how much fun you're having, how you play and relax. That's really REALLY important, brother! I was incredibly stressed out before leaving (well, getting fired from) my last corporate job for a trumped-up 'conflict of interest'. The difference in quality of life is HUGE! I have been getting regularly bodywork almost every week, plus working out, earthing / grounding , flirting with cute girls and setting up dates, enjoying live comedy, taking a social dance class (DO IT!), live music, jazz clubs, wine tasting, Paint Nite, solo trips domestically or overseas, learning a new language (Pimsleur), and just continually reinventing myself. I've done my best to eat clean, minimize wheat / dairy / excess sugar and only occasionally drink alcohol. I get high off life...! Giovonny has been and continues to be an inspiration for me.
Roosh asks us - what's your campaign? Work needs to support your broader campaign in life. Again, that Dick Richard's book is gold - you've got to work through it man, cause I'm not hearing anything about what your unique genius is and for a self-employed business owner asking questions you are, you NEED to know what makes you unique. If you can't answer that in a month or less (the book will take you a week to get through if you're into it) then you probably aren't cut out to be an true entrepreneur. I don't mean a wannabe 'I've got the next big app yo!' type (I know that's not you), but someone who is BURNING with passionate, purpose, intelligence, and growing wisdom.
It's gonna hurt, it's gonna suck, it's not all roses and Russian gymnasts jumping on your dick. You stick with it because you know WHY you're doing it and you would do it whether or not someone's paying you - but you'll make damn sure people pay you well for the excellent service and insights you provide. If it was easy, everyone would do it - the ones who fail don't know WHY they're doing it and lack the GUMPTION to stick with it. If you're willing to dive into a heady but powerful read, you may consider 'Zen and the Art of Motorcycle Maintenance.' Don't let his angst get to you, we can talk about it after you finish - and you really do need to finish if you start it - but read that book after starting 'Is Your Genius At Work?'.
From my perspective, I wouldn't trade being self-employed for double the income. Men naturally take longer to fully mature, and the self-employed man longer still - but the wisdom and relaxed self-assuredness you gain is priceless. Don't compare yourself to anyone else - you might end up with different friends, or fewer friends, because only another entrepreneur will understand you. That includes family, too. Anyone who doesn't burn - and honestly, no W-2'er I've seen really does - isn't going to stoke and encourage your fire. You are the 5 people you spend the most time with. Be very selective of who they are.
If you want more personalized insights, PM me - but get the Richard's book first. For the time I've spent writing this, I would charge a client over $150 for a consultation. I never did that a few years ago - even for an initial consultation - but I do now. Because I know every minute they share and engage with me is creating massive value in their life and understanding. I am more expensive than anyone else in my field and I am totally confident that the right customers will pay me because I create value for them, I care about them, and they will also send me their friends, family, colleagues, help me network, etc.
Business is really about relationships and connections. I find people fascinating. Even though I consider myself an introvert I love to engage with people. I've learned to listen at least 30-50% more than I talk. I've learned to draw people out with questions, to pick up on subtle things they say, or words / phrases they repeat that indicate their values. You have to be interested in psychology to be a good business person. If you don't know your Myers-Briggs type you might want to find out. I'm INFP / ISTP (clear more INFP when in the role of counselor/advisor).
If you're feeling at all depressed, I hope you are more encouraged now. Again, feel free to PM but please go through the Richard's workbook - this is a perfect time for you to do it!
