well... actually no, you can get away with not being able to draw and use flash.

You do have to think visually and you do have to have a basic intuive sense of computers, also you really really really really need how to manual and you should find some forums to ask questions about how to do stuff....

Also a basic working knowledge of a creation program, such as photoshop or painter. but you can do it with out those as long as you have a program to make things in.

Flash is not simple, but it's fun. you can do some really really great stuff with it! (I am still learning it.... and it makes me say many words that you can't say on tv!)
