A related habit of mind is to view your running like you do a committed relationship. You’re in the relationship because you want to be and your life is better because of it. Yes, sometimes you’re going to feel like you’re doing all the work and getting nothing in return. Little things might really irritate you. Others’ relationships, or former relationships of yours, might look great from a distance. But that doesn’t mean you just walk away from the relationship because you’ve hit a rough patch. Stay committed, and soon enough your devotion will be rewarded and you’ll appreciate anew all that keeps you in the relationship.
