How do you handle the worst-case scenario when it happens?

No matter how good things are at a certain moment, things can radically change in a week, a day, an hour, one minute, a second … think about a millisecond. You get to be fired from your dream job, your main business partner leaves you, your accountant hidden few millions of dollars from your books, you are thrown out of the market by a competitor, you have a car accident … and the list can go on and on. Nobody wants to hear about those but … the reality is that shit happens with the speed of light both in life & business.
