There’s a difference between wanting more and settling for more.
Wanting more is a never ending quest to achieve some pinnacle of satisfaction, only to discover there is another summit to climb that could meet even greater desires.
Happiness in this route happens in fleeting moments, only to be replaced by the disappointment of inadequacy compared to others.
Settling for more, on the other hand, forces us to aim high and settle for what we hit. We might hit the target, be just short of it, or hit an even higher target.
Whatever the outcome, there is no feeling of disappointment.
