In my last message, I talked about my commitment to run every other day up a hill that's very steep--rain or shine. No matter what.

To many people, that seems rigid. But it's the commitment I made to myself. I've learned a lot about commitments from running up that hill more than five dozen times.

I've learned that a true commitment isn't ever contingent upon convenience. Otherwise, it's not really a commitment. It's merely a decision based on current favorable circumstances.

A true commitment means, even if the nothing goes right, and no one is watching, I'm still going to do what I said I was going to do. There's a big difference.

A true commitment requires us to replace weak questions that give us an out, such as "Is skipping this once going to kill me?" with more powerful questions that render us choiceless: "Since skipping out on my commitment is not an option, how can I make it happen today?"

A true commitment doesn't even start until the original plan goes out the window.
