Sometimes it’s easier to criticize than to praise. We all know that timely, constructive criticism can erase mistakes and reverse organizational decay. But it’s praise that fuels a company’s progress, that bolsters people’s confidence and spurs them on to greater things. Winning managers look for opportunities to praise—for the person who stays late to finish a report, or helps seal a complicated deal, or points out a way to cut costs. The achievement doesn’t have to be large or dramatic. Anything that reflects a commitment to the company is praiseworthy.
