Trust. Not Greed

If you want to succeed in business, greed is optional. Trust isn't. More or less a paraphrase of Warren Buffett (via SwissMiss):

We only want to link up with people whom we like, admire, and trust. … We do not wish to join with managers who lack admirable qualities, no matter how attractive the prospects of their business. We’ve never succeeded in making a good deal with a bad person.
