"Unless we change our direction we're liable to end up where we're headed."

A lot of it has to do with attitude. People tend to look down on "positive thinking" as a tool of the self help guru's. The truth is the environment around you tends to reflect your attitude. If you approach a situation with a bad attitude then that situation will tend to prove the validity of your attitude. on the other hand if you approach that same situation with a good attitude that same situation will tend to prove the validity of that same good attitude.
