I have always liked Terry Crews, and I found this video (part 1 & part 2) very informative, particularly, for younger people.
"It's not what you know, it's what you do"
"Are you missing your purpose?"
"Instead of sitting around talking about it." Do something.
Reminds me of the movie. What about Bob, with Bill Murray.
