Make believe

When you're young and the world is your oyster, you dream dreams. You make believe.
Soon, as adulthood comes, you loose the idea that 'anything is possible' and can too easily become a cynic.
Realism allows us to accept that although it's not true that "we can be anything you choose" - as we can't - but what we can do is work to fulfill our potential and help others to do the same.
