"We don't stop playing because we grow old; we grow old because we stop playing"
Life is hard, let's be honest. As we get older we focus on our daily struggles like paying the bills, getting to work on time, making dinner, working out (maybe) and worrying about our kids and partners. There aren't enough hours in the day to get the work done. We push ourselves harder and expect more and wonder when we will break. There's no time to play when the work just keeps coming.
