I've been doing art for as long as I remembered. When I was kid, I had lots of those books where you trace and color the image and I had a lot of stenciles and wrote a lot of stories... mind you, stories from a 6 year old are not all that fantastic. Before the age of 6, as far as I remember, they didn't really support the arts in any way, so I didn't really get to do it, so when I was finally put into a family, they gave me stuff to draw and lots of paper and what not, so think it just took off from there.
I struggled a lot in high school because they pressure you to not see art as a career so I went into pre-veterinary program, but after flunking chemistry because I don't test well with problem solving questions, I went back to art and found a different college. So I went into animation, struggled with it but found it very interesting, tried some 3D and struggled so badly with it that I broke down in one my classes because I just could not do it for the life of me and was just frustrating my teacher... so after that I tried game and character design, love it and finished college under the game design category.
College was probably my 'aha' moment because the artwork I produced there skyrocketed in style and concept compared to the work I produced before college. The difference is almost scary (at least to me) and I also got to write and create stories. I loved creating stories. It was my most favorite class where we had to create a story for a game, develop the environments, characters, and overall visual look and feel of the game. Loved it to death and thus its now mostly what I do. Though I also do graphic novels alongside game design :3
