'Hara Hachi bu' means eat until you are 80% full. Life is not a sprint. Part of the skill of Endurance is the ability to hold something back. Full Commitment may seem like you need to give everything to every situation. That is short-sighted. Truly caring about things means you detach a little. Detach 20%. Keep a little bit of space. This enables you to keep things ticking. To focus on the basics. The mechanics. Eating, breathing, relaxing, exercising and building constructive patterns of thought. Then you can dive into the relationships and creative exercises that give life meaning.
