That would make a fine tag line.
Not nearly as pithy as yours, but here's some words to live by from Ayn Rand:
"I don't like people who speak or think in terms of gaining anybody's confidence. If one's actions are honest, one does not need the predated confidence of others, only their rational perception. The person who craves a moral blank check of that kind, has dishonest intentions, whether he admits it to himself or not."
