If You Have A Strong Opponent, A Competition Is Stimulating. I Am Generally Most Open To Ideas When I Have Had A Bad Result. In Chess, Too, Players Specialize. This Specialty Then Becomes An Entry Barrier.
A good leader can engage in a debate frankly and thoroughly, knowing
that at the end he and the other side must be closer, and thus emerge
stronger. You don't have that idea when you are arrogant, superficial, and uninformed.
