go there man. Than find a shitload of tutorials and just make shit that looks good, and eventually you start learning and picking shit up easy. That's what I did, I find my FAVORITE hot key on adobe photoshop (7.0) is
CTRL+ALT+SHIFT+~, I fucking love that, it selects all the white areas. It can be VERY useful when doing shit, and like you can select the inverse of it too.
Never stop learning!
