People have an insatiable need to be appreciated.  If you can satisfy this need, you will have them eating out the palm of your hand.  One very easy way to do this is to complement people, in a sincere way, for any number of reasons: things they have accomplished, the outfit they are wearing, how much you like their new hair style, the fact that their smile seems especially bright today or that you really appreciate having them around because they add so much to your life.  You’ll find that taking the time to pay people sincere complements costs you absolutely nothing, but it does produce some very tangible results in terms of people lining up waiting for a chance to do you a favor.  – RossReck.com and InstantTurnaround.net
