If you want to put something into practice right now, then you might consider working on how you talk to yourself. Not how you are "exhibiting" to others.
You aren't "less than". You just keep telling yourself that you are, because it conforms to some deeply ingrained image you have of yourself that has been with you since you were too young to know any better. You are old enough to know better now, so you have to be nicer to yourself.
Dishes break. Feelings get hurt. We learn and we try do better next time. But all the self-flagellation in the world doesn't change something that has already happened.
