When you are thinking ask yourself if it is serving you. If it isn’t consider pure action instead in the absence of intentional thought. Try not thinking and only doing the very next thing there is to do only. Work at it. There is nothing wrong with thinking but it sure would be nice to not have to. Try more unabated action instead.
Fall in love with no resistance to what is and watch what happens. This isn’t to imply that you never do anything about it.
