How about confidence in being able to stand up for what’s right?
Confidence in the bravado sense is BULLSHIT. But having security in your ability to do the right thing, isn’t.
You could be a flaccid pasty white (or dark chocolate- no need to discriminate here) couch potato and be 100% in the right but couldn’t do the right thing when it came to physical tactics. You could try, but you probably would get your ass handed to you.
Confidence comes from knowing your ability to do the right thing if you had to. Doing the right thing gives you proper motivation and conviction.
