In order to be successful in any arena including spiritual life, you have to conquer the mind. But we conquer the mind, as krishna says, by tolerating the happiness and distress. So how to get better at tolerating happiness and distress? Purposely bring on more uncomfortable situations and build you emotional resilience to tolerate what is going to come anyway. Why not prepare yourself like a Navy Seal and get better at being uncomfortable. Become comfortable with being in uncomfortable well.
