Learn to adapt. Figure out how you can live through any and every situation. Why? Because things in life constantly change. Yes you have your own habits, and set patterns, but you can’t always know when natural disasters will strike. You won’t always know who’s out to get you. You may get layed off, you might not make it to that even on time. Divorce may come. You may even be thrown off by recent success that you’ve earned or obtained.
Regardless of what happens to you, it’s important that you are able to improvise, adapt, and overcome it all. Always be ready.
