I’ve heard it’s a skill that you can improve upon. Controlling stress and mitigating internal damage from major stressors is still very difficult for me after all of these years of working on it. Outwardly, I think I can march forward, but I still allow certain stressful things to get in the way at the worst times.
Acute, but temporary stress is good for my system and makes me a better practitioner in the end. I just need to work on being more graceful in the beginning and middle parts.
