In moments like these, don’t think, just do. Think about what you want to do and then stop thinking altogether and start going to do what you want to do just repeating “don’t think just do” to yourself the whole time you are walking to do what it is. Don’t think about anything while you are walking to do said thing. If your brain says stop, do not listen to that shit. You already did all the thinking before you started walking. Don’t start thinking again until you have already started doing said thing. This shit works for me at least
