The Best to your Ability?

Do the best to your ability. That phrase kind of puts a limitation on what you can do. What if doing the best to your ability isn’t enough? Can we push ourselves further? What if looking “good enough” or godly to others doesn’t cut it for you deep down? The question is are you giving it your all? Are you striving for your highest performance? Or are you just getting by by doing your best? I want to thrive by meeting challenges and stepping outside my comfort zone, not just floating along in life on a whim. 
This book Do Hard Things is really putting me to the test.
