I only have one song that I can associate with a life-changing event.
Fall of 2012, I just got dumped by my then-gf, who I had adored, and put myself through hell so she could "figure things out" by giving her space. She ended up leaving both me and the office we worked in. At the same time, I was preparing for a talk where I had to ask a committee if I could move on to writing my thesis. This was stressful in itself becauce a 'no' would have meant me staying back for at least another year, something which I was desperate not to do.
One Sunday afternoon, I was in my lab working on this huge talk, which was about an hour long, when while going to take a leak, I see her walking down the hall towards me carrying some of her shit out of her old office. I ducked out of the way, and let her do her thing. About two hours later, I went to out lunchroom to get a tea. On the central table, was a container of expensive hand cream that I had bought for her as a present when I was out of the country presenting at a conference earlier in the year. She had evidently found it while cleaning out her office, and put it on the table for someone else to take. It was an act that was unbelievably cruel to me, and almost broke me right then and there.
I got back to the lab, and tried to work. I ended up putting a talk together, but I wasn't happy with it, so I started again from scratch. During this time, my mind was still spinning from the lunchroom thing. I thought about how I had done everything right: been a good man, a nice person, stuck by the idea that if you do good things, then good things happen. I realised, right then and there, that even if you do all of that, there's no guarantee of something good coming from it. It was a life-changing revelation. I also thought about how I could ever deal with this, and how was I ever going to pass this test with this going on in my mind. It was at this moment, this only moment in my whole life, that I thought about whether I should just punch out permanently right there.
I got on the lab computer, and started looking for something to cheer me up. I remembered the song 'I Get Wet' by Andrew WK was in a fan-made trailer for 'The Expendables', and I put on the live version where Andrew plays the piano in the lead up. When I heard it, something upstairs flipped in my head. It was from despair, to joy. I listened to that song a few more times, and it made me happy for this first time since about June. I went back to work on my presentation, and went home at around 3am with it done and saved.
I went to my meeting the following Wednesday, and killed it. I was back on the course to being happy and positive. Of course I still had a lot of things in my head to get over, but that Sunday night was a marker; I no longer was afraid of running into people cleaning out there office; and I knew that I was almost done my studies. That was the moment where the 'red pill' was well and truly taken. I had seen the world for what it truly was.
Since then, I've had the time of my life, sleeping with lots of women that I never would have had the balls in a million years to talk to, let alone take home; standing up for myself when people did bad things; improving myself as much as possible; and owning up to mistakes I had made, and moving on from them. I have also realised that the actions of this person were my fault. I let her walk all over me; let her do things to me that I never would have tolerated from anyone else because she was my 'girlfriend'. I realised that my happiness is paramount; and that being nice and gentlemanly all the time to a women will eventually lead into them hating your guts. I'm at a point now where that behaviour by me will not happen again.
Anyways, f'k it. Here's the song that got the ball rolling.
