Few of us spend much time practicing thinking skills. We believe that thinking is either a natural function that requires no learning or believe that the great thinkers among us are naturally gifted and not the same as the rest of us. Nothing could be further from the truth. All modern research shows that each of us has a hugely powerful potential in our brains that in nearly every instance lies vastly under-used. Moreover, when faced with a wide range of unsolvable problems in our lives, the need to use this potential has never been greater.
