Video editing. Used to be really good at VFX and shit. I probably still am. Worked a few editing jobs before I realized I wanted to be in front of the camera rather than behind a monitor. Now I spend time practicing acting and comedy instead.
Used to play a lot of computer. 4000+ hours on Gmod with many being on Perp. Now I can't play any game for more than an hour without being bored to shit. Never really turn on my computer anymore.
I also used to masturbate a lot. Don't need to anymore.
