How do I stop sacrificing my health for work?

You skip exercise, eat badly, and sleep poorly because work takes the time and energy those things need. It feels like a temporary trade: health now for progress, to be repaid later. But later keeps not coming, and the body keeps a quiet tally the whole time. Your health is not a resource you can borrow against forever. It is the platform everything else stands on, including the work you are sacrificing it for. A tired, unwell version of you does worse work anyway, so the trade does not even pay off on its own terms. You are spending the thing that makes all the other things possible. You do not need a total overhaul. Pick one thing and protect it this week: a real bedtime, a short walk each day, one proper meal. Put it in the calendar like a meeting you cannot miss. Small, consistent care beats a grand plan you never start. Your body has been patient. Give it one thing back.
