Praise takes little effort to create, is risk free to distribute and rewards those who dispense it. Valuing praise at its cost of production, praise is worthless. Yet, most people love being praised and pay handsomely those who praise them, who often appear in the role of salespeople. Criticism takes thought, effort and is a thankless job; often received as umbrage. I feel those who criticize me love me and my criticism of others is given out of love. Maybe that's why I was never much of a salesman....
