Let me be clear: I'm a believer in a robust military, which is essential for backing up diplomacy. But the implication is that we need a balanced tool chest of diplomatic and military tools alike. Instead, we have a billionaire military and a pauper diplomacy. The U. S. military now has more people in its marching bands than the State Department has in its foreign service - and that's preposterous.
Perhaps the most important thing I could say is to never be thrown by failure and mistakes. Each and everything that happens, even if it was not what you hoped would happen, is a valuable, life-learning tool. And you will only achieve success if you know how to learn from your failures and mistakes. It’s vital.
