My dream is to become a cartoonist and have a cartoon on maybe...cartoon network? or other networkes(but I'm aiming for cartoonnetwork) I know I have the talent to do it, and I love to draw! and I don't mean to brag but, I draw cartoon characters very good

I think I won't be able to get in. I watch cartoons all the time, and I think, wow...how did they get noticed? it must be great what there doing.
so I get depressed and think I'll never have my show

Ever since I was 4 years old I thought of cartoons and making them.
What do you guys think I should do to get a better chance of having my dream come to life?
