You might fail at your job or with your family, lose a loved one, suffer a serious accident or illness, or discover the life you imagined is out of reach forever. There are a whole host of ways that something will get you . At such times, you will be in pain and might think that you don’t have the strength to go on. You almost always do, however; your ultimate success will depend on you realizing that fact, even though it might not seem that way at the moment.

This is why many people who have endured setbacks that seems devastating at the time ended up happy as (or even happier than) they originally were after they successfully adapted to them. The quality of your life will depend on the choices you make at those painful moments. The faster one appropriately adapts, the better. No matter what you want out of life, your ability to adapt and move quickly and efficiently through the process of personal evolution will determine your success and your happiness. If you do it well, you can cahnge your psychological reaction to it so that what was painful can become something you crave.

The most valuable habit I’ve acquired is using pain to trigger quality reflections. If you can acquire this habit yourself, you will learn what causes your pain and what you can do about it, and it will have an enormous impact on your effectiveness.

Look for people who have lots of great questions. Smart people are the ones who ask the most thoughtful questions, as opposed to thinking they have all the answers. Great questions are a much better indicator of future success than great answers.
