First, consider the pen you write with. It should be a fast-writing pen because your thoughts are always much faster than your hand. You don't want to slow up your hand even more with a slow pen. A ballpoint, a pencil, a felt tip, for sure, are slow. Go to a stationery store and see what feels good to you. Try out different kinds. Don't get too fancy and expensive. I mostly use a cheap Sheaffer fountain pen, about $1.95.... You want to be able to feel the connection and texture of the pen on paper.
