Create the loftiest of goals for yourself as a writer! If you don't have lofty goals, you won't achieve anything lofty. Have I said lofty enough times?
But seriously, challenge yourself to write two or three pieces a week, go after the publications you never thought you could get published in, and get coffee (or ice cream, if it were me) with and learn from the writers that inspire you. It's not always a bad thing to be hard on yourself—that's how you grow!
