How Will You Measure Your Life?

Here is an interesting article I found today, How will you measure your life?
It's written by HBS prof, Clayton M. Christensen , At the end of his class, he let his students discuss about below 3questions,

1. how can I be sure that I’ll be happy in my career?
2. how can I be sure that my relationships with my spouse and my family become an enduring source of happiness?

3. how can I be sure I’ll stay out of jail? ... lol :D

Try answering questions above , you might be able to clarify your own way to pursuit of happiness in your life. ;)
