I don't know about the giving up sleep part, but besides that I believe this 100%. Most my high school classmates who had the same or more abiility as me aren't shit because they don't want it bad enough. They would rather be Mr Instagram, ot Mrs Facebook, or just want to party too much and have no goals.then they bitch about being poor, well, you made that choice dumbass. To me, life is about living up to your potential and being all that you can be, and I wont stop working until that happens.
