J.J. Watt's motto is "dream big, work hard" because he did both of those things growing up.

As a walk-on college football player turned NFL MVP candidate, he likes that quality in others, too.

Watt received a letter recently from a 7-year-old whose friends call him J.J. because he also plays defensive end and tight end. Dreaming big, the kid autographed his own jersey and sent it to Watt so Watt would have it when the kid became a famous NFL player, just like Watt.

As expected, Watt approved of the kid's chutzpah.
