 Time is our most precious resource because that is finite. Whenever that's done, that's done. We don't have any more of it. Energy is something, though, that we can actually replenish. And a lot of that has to do with our routines and our self-care. Most people would freak out if they looked down at their iPhone and saw their iPhone had three or 4% juice left in it. They'd immediately start looking for a plug or a Mophie or something, but they allow themselves to go down to three or 4% and they don't seem to do anything about it. And then you're just running on fumes.
