A little praise and encourgement can boost the morale of your employees.
Does your boss praise and reward you for a job well done? Does your supervisor let you know where you can improve? Do you like where you work? Do you like your customers?
While it is impossible to completely change someone else's behavior, you can modify yours. You can also change how things affect you. The way to begin is by using praise or compliments to respond to the world around you. Being positive is more difficult than being negative, but it is rewarding.
