"Look where you're going, not where you are."

Words of wisdom from my former skating coach, that also apply to life. 
She meant it literally at the time, because if you look straight down doing figures in skating, you'll fall on your face. You must look ahead to see what's coming in order to make adjustments and adapt. 

Life is constantly changing. The things that happen to and around us are actually devoid of meaning, until we as humans give them meaning.  Don't let your present circumstances limit your vision for your future.
