The best thing in life to get the better of is the desire to better than the best. That’s an external drive with (at best) only momentary validation. The internal drive to be better than you were yesterday so you can be your best self today is renewed every waking moment. That’s sustainable, even on days when it feels unrealistic. If you can vanquish the desire to be anything more than the best you can be in the moment, you’ve defeated the worlds greatest rival…the Ego.
