An extreme version is to work for energy, not money. Instead of choosing clients, customers, markets, suppliers, angels based on profitability (or future profitability), base it on energy. There's a reasonable probability that energy will translate into value creation and then into money, anyway. And even if not, would you rather be full-of-life and poor, or half-dead and rich? (to dichotomize for dramatic contrast.)
