I think the part that begins "I like myself on the following conditions..." is just pointing out how we tend to not like ourselves because of "faults" that aren't actual faults at all. You don't have to be better than the next guy, or good-looking or any of that. Even if you were, next you'll just be chasing money and power. The point is, don't waste your time on these things because you'll never get enough of it.
