I'd much rather be around people who questioned themselves and their motives on a regular basis than around people who thought everything they did was right and good and above reproach.

How are you at not beating yourself up? If you're really hard on yourself for normal human errors, that's probably more of a problem than examining your actions. I take an inventory of my actions every day and make corrections if necessary, trying to learn from it as I go along. As long as I'm not mean to myself for making blunders it's a helpful exercise.

I wish you the best and hope you're not too hard on yourself.
