Iirc Allen Watts likened obsessively thinking about yourself to two monitors facing each other (highlighting the discordant feedback).

While I still have cringe-moments when I remember things I've done (as a kid, 10 years ago, whenever), I try to remember that I am what I'm doing. For me, it puts legs on the concept of remaining in the present. Whatever self others ascribe to me, that's fine, but I don't have live by those expectations. When I'm folding clothes, brushing my teeth, writing something, taking care of the dogs, etc., I'm no more or less than what I'm doing. It eases my mind and lets me focus on the given task. With practice, I don't have to think of it as much. It becomes the natural way to approach things, but there are still times when I have to remind myself.
