There are more direct approaches, but, recognize those thoughts as bubbling up from lower levels of brain function, that they are not who you are nor are they your destiny nor are you required to act upon them, leave them be, and do what you need to be doing, with your attention on the doing. If you engage with the thoughts (by trying to change them or suppress them or argue with them), you simply strengthen the associated neurology. If you respond to the thoughts with avoidance, you strengthen that associated neurology.
