"In my heart and in my head, not in my pockets"

I just read this story about a janitor who recently graduated from Colombia University. Since staff there can take free classes, over the years he earned a bachelor's degree in classics. I love the bit he says at the end regarding his motivation for pursuing a subsequent graduate degree...apparently not to make more money (how much can you make with a master's or PhD in classics anyway?)

"The richness is in me, in my heart and in my head, not in my pockets."

Pretty deep, for a lowly janitor. His attitude reminds me of this carpenter they wrote a book about once...
