I try to believe I can, but people always tell me I can't.......I posted the stories I wrote here and on FanFiction.net, but all people tell me is I can't write......I know I can use their complaints to improve, but my own muse says I should give up drawing and writing.....So I guess it's a good thing that I'm more stubborn then any mule.
You just have to find people that tell you you can. Find and make good friends. Surround yourself with them and not the bad people. It is a good thing you're "stubborn". Call it not giving up on a passion.
My one friend says she would hit my muse for putting me down if she could! She says that while my writing needs a little practice, I'm the best artist she knows. So she's teaching me how to write better, and in exchange I teach her some drawing tips.
