Celtics Weight Room Quote

"What hurts more, the pain of hard work or the pain of regret?"

Love this quote.  It can be found in the Celtics practice facility above the weight room entrance. This reminds me of a book I read about the life of "Pistol" Pete Maravich that revealed a similar philosophy of Pete growing up.  He practiced and trained for hours because he was afraid there was someone in the world practicing at that very moment getting better.  He couldn't stand the idea of playing against someone in the future who possibly put in more practice hours than he did and this fear drove him into the hours of practice that turned him into one of the greatest ball handlers and shot makers of his time. 

Pistol Pete chose the pain of hard work over the pain of regret. Which are you more fearful of?
