Don’t let the words get in the way. If you are writing online, forget everything you were tortured by in high school English class. You are not trying to win any awards or get an A, are not writing a thesis report with Harvard style references.
You are just trying to be real, to make a point, to write something worth reading.
So just say it.
No thinking – that comes later. You must write your first draft with your heart. You rewrite with your head. The first key to writing is… to write, not to think. – William Forrester
