This is a great motivational sign for any sales office.
I came up with "Give a man a fish he will eat for a day. Teach a man to fish he will eat every day, but give him a stick of dynamite and everyone eats" and "Crystals and runes may bend spoons but fire will never burn me" ages ago and I see them on other sites with other people attempting to take the credit but hey, I'm too experienced to care.
I take it as a compliment when I see it. I recommend that you all put something like this up in your office or salesroom and remember that along with "Never, ever, quit!" 'When in doubt, just sell' is a great way of life.
Keep on cracking your rat!
PS. "Do you sincerely want to be rich?"
