Doing something, even badly, is much better than not doing it at all (as the wise Jim Munroe once wrote on his blog), because something is better than nothing.
Anyway, if like me you agree that (specifically) writing is better than not writing, go ahead and sign up for NaNoWriMo ([inter]National Novel Writing Month). It's starting tomorrow. Oh my. November somehow seemed further away than that.
Right now my "do something badly" thing is going to be blogging. And as The Artist's Way reminds people, it's normal that you're bad in the beginning. Later you could get good.
