Since I started running in January, I’ve noticed something that, while not incredibly surprising, is still new to me: while I’m running, I feel stronger, more physically capable, and healthier. It’s a reliable way to experience eustress on a scalable level.

What’s more, when my body feels like it’s functioning as it should, the quality of my thinking improves as well.

Physical strength leads to clearer, more optimistic thoughts, and less ego-driven thinking. When I’m not using energy to build up defenses, it’s easier to be more kind, humble, friendly, empathetic, and loving.

In short, feeling physically strong makes it easier to think strong thoughts. Running is a simple, scalable and reproducable way to achieve that.
