I'm a cardiologist. Some of the most exhausted hearts I see belong to people with no blockages at all. They are replaying a conversation from 2019. Rehearsing a disaster that hasn't happened. Demanding certainty from a life that never offered any. The Japanese have a phrase: shikata ga nai. "It cannot be helped." It isn't surrender. It's refusing to spend your strength fighting what can't be changed, so you have some left for what can. One question does most of the work: Can I do something about this right now? If yes, take one step. Not the whole solution. One step. If no, put it down. The past can't be edited. The future can't be guaranteed. Your body pays for every hour you spend in either one. Overthinking rarely comes from having too many problems. It comes from replaying every mistake, controlling every outcome, and demanding answers life was never going to give you. Do what you can. Release what you can't. Some things cannot be changed. Peace starts the moment you stop arguing with them. Shikata ga nai.
