Jim Kwik says resilience comes from deliberately choosing hard things: cold exposure, sauna, exercise, meditation. Comfort in discomfort makes life easier later. He also stresses self-compassion, letting yourself feel bad without judgment when things go wrong.

One of the things that gets me through difficult times is to exercise my grit. Having some kind of resilience practice. Building resilience through practices like cold therapy or sauna or mindfulness or physical exercise, meditation can help you because it enhances your ability to cope with stress and recover from adversity. So build that. Doing those hard things ultimately will make your life easier. If you just do the easy things in life, life gets hard. But if you do the difficult things, then life gets easier. When you can find comfort in being uncomfortable, with challenge comes change. I would also say, remember the power of self-compassion, the importance of it. Being kind to yourself during tough times is absolutely crucial. Allow yourself to experience and express your emotions without that judgment and recognize that setbacks are a normal part of the human experience.
