The one thing that you must know

What is the one thing that is critical to you? 

Is it the family? 

Is it the career?

Is it money?

We all want it all. But you must know what that one thing is that you will regret the most, if you dont get it. 

When you are on the rocking chair. And cant turn back the clock, it will be terrible to come all that distance without knowing what that thing is. Worse, if you spend all your time and energy trying to get after the "wrong" thing, regardless of whether or not you achieved that or not

So do you know what that thing is for you?
