One of the biggest mistakes people make is concentrating on one source of income. They think that if they stay at one company they’ll eventually get rich. They think that if they work hard and perform well they’ll move up the corporate ladder. They think that if they keep getting raises, they’ll eventually make enough money.
But what happens if you get laid off? What happens if the industry you work in suffers economically? I’ll tell you what happens. That one source of income you’ve been relying upon is suddenly not so reliable.
