I like to run for exercise. Running can be done just about anywhere, it doesn’t require equipment, I can do it solo, and there’s no special ability required (I just adjust my pace accordingly). In fact, I've ran five half-marathons (none of them very fast, mind you). When I train, I work on improving my physical endurance, my speed, AND my mental fortitude. These three mindset shifts have revolutionized my running performance AND, interestingly enough, my financial well-being.
