Yesterday I watched  some of my children play on a thirty-ton boulder that had been pushed by the  winter ice one hundred yards from the interior of the lake to the beach.  H2O, three small atoms forming one single molecule, joined to others and then once  frozen pushed thirty tons 100 yards over 60 days.  Something microscopic overcame a significant challenge with time and continued energy.

 Watching my children play on that boulder I thought about how persistence and determination eventually outlast any challenge. 

If you struggle with something that is meaningful, persist. Be determined. Don't give up. Eventually, all obstacles, regardless of the size, are overcome by persistence. 

“Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'Press On' has solved and always will solve the problems of the human race.”  —Calvin Coolidge
