One of the only times when I really felt like I accomplished something, was getting Hideo Kojima's autograph. I know, it sounds sad even to myself, but it was something I really wanted for 4+ years of my life and it was finally within my grasp. When I was younger I seriously had dreams about it. Lining up for 10 hours despite having two hs exams the next day (which i passed). Finally getting it, I was probably the happiest I've ever been for two days.
Second was when I finished high school and got through my awful Christian private school finally, spending a whole day going to graduation parties and just chilling.
Other than that there isn't much, really the only thing I want is to finally make a short film that I am happy with, but I don't see myself getting on a set anytime soon.
