The worst part about the whole "growing up" thing is: The seed of doubt that forms in the head. I made a big mistake when I was 16 years old: I GAVE UP VIDEO GAMES Why?* Because I thought it was "for kids".* I was wrong for believing them. I'd be a video game designer by now. I don't regret a thing that I've done so far, but I am annoyed that I listened to the naysayers, because millions of people listen to the naysayers and stop pursuing their dreams. Do what interests you.* All that maturity stuff is a load of junk.* the hardest part though, is getting rid of that "seed of doubt".* It's planted in our heads when we're REALLY young [ "don't be a baby! we're told when we're 3 years old" - and we keep getting told that] and hard to shake it.
