Train not just the mind, but the heart as well. The mind knows, but the heart governs. Wisdom here from our dystopian buddha.
Much of the notion of the comfort/discomfort of an activity comes from the connotation we put on it—”I like/hate this.” “I’m good/horrible at this” “this is boring/fun.”
Training should be more than just a mindless acquisition of skill; it should be a conscious deprogramming of that which keeps us inept.
