What makes a person successful ?

Perhaps, it's a question one would have heard and read many times. And there would have been that many answers to it. None right, nor wrong.

Let's not talk about the process for the time being. Let's just consider the end point of that process. So, what exactly describes success. Is it just a state of mind ? Or, can it be measured using some parameters.
- bank balance ?
- name and fame ?
- popularity index ?
- network ?

If you cared to read this far, why not spend 2 minutes to describe success in your own words. I am sure most of us will find it difficult to make up our mind on the definition of success. What's your take ?
