“Take the attitude that what you are thinking and feeling is valuable stuff, and then be naive enough to get it all down on paper.” – Anne Lamott
And *naivete can serve you well.
Write something today you haven't written because you thought it was a worthless idea.
*(Please mentally insert accent mark over final "e", as I don't know how. Yes, you can still write, blog--anything--even if there are things you don't know how to do. Focus on what you want to say.)
