When You Let Go of 'Attachment to Results,' Your Best Self Emerges

The book advocates an approach of 'cultivating the excellence within yourself (Inner Excellence).' It systematically teaches how to let go of attachment to outcomes and ego, and instead focus completely on 'this very moment,' enabling you to maintain composure under pressure and bring out your best self.

'Those who continue to grow focus not on results, but on this very moment'—this is the definitive guide to mental training, encompassing insights from Maslow's psychology to Navy SEALs leadership.
