America must always lead on the world stage. If we don't, no one else will. The military that you have joined is, and always will be, the backbone of that leadership. But U.S. military action cannot be the only - or even primary - component of our leadership in every instance. Just because we have the best hammer does not mean that every problem is a nail.

That's what building a body of work is all about. It's about the daily labor, the many individual acts, the choices large and small that add up over time, over a lifetime to a lasting legacy. It's about not being satisfied with the latest achievement, the latest gold star, because the one thing I know about a body of work is that it's never finished. It's cumulative. It deepens and expands with each day you give your best. You may have setbacks and you may have failures, but you're not done.
