Dare to challenge yourself with fantastic goals and work with an eye towards those. The idea is that when a person that’s aiming high falls short, they go further than someone who doesn’t make the same effort.
I’m not sure this logic is healthy…
Those that press towards the fantastic are seldom satisfied or content. The carrot is forever out of reach.
Instead, challenging yourself for the sake of entertainment is an open ended goal and by definition of being motivated by self entertainment, the struggle itself is very satisfying.
