Your energy doesn’t keep forever. You aren’t a battery. You need a flow of energy, in and out, to stay healthy and realize your goals.
It would be wonderful if we could wake up in the morning with a lot of energy, realize we didn’t have much to do that day, and somehow roll that energy over into the next. But that’s not how it works. You’ll need new energy tomorrow, but what’s more – you need to find a way to use up that energy today.
If you don’t, it goes stale. It starts to rot. It comes out in other ways: as anxiety, as fidgety distraction, or as bad habits. Every day you have to both empty and fill the tank within you – you can’t skip either.
