Resources for guilt loop

Hi! I just started The certification Program and have noticed between starting to coach volunteers, my own coaching and in the coaching calls, that we have quite a lot of guilt beliefs in our brain and it seems interesting that sometimes taking credit for the successes can be challenging but taking credit for failures seems just easier. I was wondering, as in the motivational triad, if there is any advantage for out species for our brain to offer this to us. Any books you can recommend on this subject? It truly fascinates me. Thank you!
