An investor spreads her risk among multiple projects. Many small, but good bets. The investor knows that most of the projects won't work out.
So she spreads her risk. She has a diversified portfolio. And maybe if she's lucky 1 out of 10 projects might work out.
An employee doesn't spread her risk. One huge bet. For life. The employee believes that she will have a great career. A safe life. Forever.
So she doesn't spread her risk. She doesn't have a diversified portfolio. And maybe if she's lucky she'll keep her job. Maybe she'll have a great career.
Maybe not. Who knows?
