What is the difference between living and existing?
When you look back on your life are you going to remember the times you decided to not try and stretch yourself and accepted what life has given you?
Or will you think back onto the moments where you gave it your best effort and either exceeded beyond all expectation or failed miserably?
Either way, you were fully engaged in the process of finding what you were made of. I believe that much of the difference between living and just existing stems from this search to measure ourselves.
