Borrowed Energy

Borrowed energy is the second wind that isn't yours. You're running on what tomorrow was going to spend. The body keeps the receipt; you'll see the charge later. This is what gets you through the week's hardest day, the late night before the deadline, the conversation you cannot afford to let collapse. There is nothing wrong with borrowing — sometimes it is the right move. But it is a loan, not income. Naming it lets you plan the repayment instead of pretending none is due.
