My brother always said never to volunteer for charity work - spend your time racking up money and donate. Not particularly useful, I guess, and I don’t see myself doing either, but hey!

_Never_ open your mouth unless you’re absolutely sure you know what you’re talking about. _Never_ pretend you know what you’re talking about when you don’t. This isn’t just an honesty thing - you’ll get burned, I promise you.

Oh, yeah. Fools rush in where wise men never go. Use this to justify cowardice _whenever possible_.
