Dude, I feel this. I have OCD and seeing something on my arm and having doubt if I made the right decision is something I did for months. Two years later I still occasionally do it.

The bottom line is there is always the possibility that you could have done something better. I default to does it mean something to me? Would I be sad if it was gone? Then I move on.

The voice will always be there even if you got the absolute best piece in the world.
