If you see success as a zero-sum game, life becomes a series of cutthroat competitions. You reach the top by taking others down.
If you see the possibility of mutual benefit, your goals shift from crushing the competition to making a contribution. You rise by lifting others up.

Waarmee overwint hij dus het veranderlijke? Met het eeuwige.
