i got into arts during my years at primary school.
my reason was because i had nothing better to do when i was home at the time.(now i watch anime and read manga)
the teachers would also ask me to do art posters and stuff.
the time i REALLY got interested was when ,y vision of art evolved u can say. i wanted to get better.
i grew tired of drawing stick people and battle airships and started working on 2-d drawings.
but ii stopped drawing afterwards.
at the end of my 1rst year in secondary school i noticed someone who drew so well i was creaped out by how his drawings turned out. i started challenging him then i got better and better( by drawing first thing in the morning, when i get to school, in classes, at gym, during lunch, on the bus, at home etc.)
u can say that by seeing someone who drew better than i did, i felt the urge to start over(competitive spirit).
my last motivation was while i was watching devil may cry the anime. it made me excited. decided to become a character designer for vid games and anime since then.so started learning how to draw males and to my surprise they mostly turn out like dante.(still working on fixing that even if it's not bad)
those r my motivations.
thing is, when life goes on, it seems to evolve. unless u have really been seduced by one motive, u'll always find a new one. either that or u'll just get bored and quit.
srry for the long story dude.
