Not exactly sure what wisdom is. Is it telling you what to do?

Never Say Never

Never take advice from a comment on an internet site or an Amazon review.

Best one liner I've ever been included upon
"Just keep breathing as long as possible."

I think it depends entirely on who you are and what your idea of a good life is. When I was learning to drive, my instructor said" focus on where you're going and the mechanics will fall into place". I've always thought that was pretty good advice all around.

Dont get caught

What works for one will not necessarily work for another. You do you and I do me works best for me. (IMHO)

Do no harm. Covers just about everything.
