Burnout is, at its core, an issue of being temporarily used up.
Think of energy in your life—both physical and emotional energy—like money in a bank account. When you rest, and invest in energizing activities, deposits are made in the energy account. In this way, energy really is a renewable resource in your life. But you should also remember that when life throws stressors at you (and let’s face it; life does that all the time), you make withdrawals from that energy account. Sometimes you make big withdrawals. But so long as your withdrawals are less than the deposits, your account doesn’t overdraft. And you’re okay.
