1)Don't stop writing. 2)Don't let anyone else's advice paralyze you or make you doubt yourself; nobody is so brilliant that they know every possible path into writing or publishing a story, particularly yours. 3)Grow a thick skin, a healthy ego, and a sense of humor. 4)Never expect it to be easy, and don't beat yourself up if it doesn't happen for you as quickly as you think it should. Everybody fails, even--especially--those who eventually succeed.
