If you cannot use them it still makes the person feel good, witch will reduce stress. You as a leader need to motivate your crew of workers. This does not mean to yell, scream and get them ready for the big football game. This will work in a few cases but not for a long period. Get them to be motivated for the long run.
Motivation is one of the two most basic and most important qualities any individual can have.
With motivation and desire one human can accomplish things that seem nearly impossible to others. Amazing things happen everyday through motivation and many successful people learn to acquire motivation and desire. To me this is what makes successful people successful. Some people run around daily with so much motivation and desire to accomplish their next task that they will nearly die to get it done, and the last thing they will do is quit or give up. These are the people you want running your day to day operations.
