Payback is a word with double meaning. It can imply something good or bad. Think karma in Buddhism and Hinduism. Karma suggests that every deed, good or bad, has its consequences. In other words, there is cause and effect for everything you do. When it’s payback time, you will see the result of your past action. For instance, you put your money in an investment. When it reaches the payback period, your investment may breakeven and you get back your initial capital. You may even make some money or a profit. On the other hand, if you owe others something, you have to repay your debt one day. Similarly, if you make a mistake, you have to pay the price when it’s payback time.
