I believe running is the ultimate business lesson—seriously. As soon as I start running, I want it to be over. But no matter how much I try to hurry it, it takes time. In business, it takes time to build something great, and you can’t cut corners—you have to start at Mile 1 and there are no shortcuts to success.

Running also gives you a lot of downtime to think—to deal with pain, joy, and all the emotions in between. It makes you commit, too. And it makes you finish: It doesn’t care how you’re feeling that day, whether you’re in a good mood or a bad mood. It requires your all. When I’m running, I have to sift through all my thoughts to clear my head, and I often find myself a victim of negative self-talk: I tell myself that I should stop, I should quit, I should walk. In those moments, I ask myself, “Are you a quitter? Are you going to let this beat you?” The answer is always no. Once I verbalize that in my mind, I find a way to power through.

It’s the same way in business. My back may be against the wall, but I’m confident that my team and I will find a way to push forward.
