Public speaking touchdown

I don't watch football, so I don't know the strategy, but while snacking on a lovely Boddington's ale and some fries Sunday in a local restaurant, I caught a few highlights of the weekend football games.

I noticed that, when the player with the ball runs for the end zone, he runs as fast as he can, even if no one is after him. You might have noticed this in other sports as well. Why run as fast as you can, even if you know you won't be caught?

Because you're giving it all you've got, or in sports terminology: "leaving it on the field."

When you run like that, you're committed. You're motivated. You're willing to do whatever it takes.

How about you? Do you walk away from every speaking engagement knowing you gave it your all?
