You have two choices in any moment. To think or to do. If you do, you can’t think. If you think, you must think then do. If you think first, you do slower. If you trust yourself, doing is easier, smoother, and faster.
If you try to think while you do, your action will be slower, more erratic, and less fluid.
Stop getting in your own way. It’s a two letter word for a reason.
