Survive. No matter what.
We have to focus on surviving—literally—at some point in our life.
When you get sick or hospitalized. When your boss is notorious for being difficult and cruel. When your business runs out of money.
If you come across such situation, you will find out the most important thing to you and figure out how to protect it. You will be tested by adversity; it can be quite tough at times, but knowledge from such experience is a true gift for your life.
