It is a very basic human characteristic that we tend to respond to others in the same way they treat us. They will always remember the kindness you extended, and someday when you need it most, help will appear from a totally unexpected source. The kindness and courtesies you extend to others need not be large and expensive. A kind word, a friendly greeting, or assistance with a favorite project lets others know that you care enough about them to lend a helping hand. When you help another cheerfully and enthusiastically without asking for anything in return, the law of compensation places that person in your debt. You have made a friend who is now interested in your success.
