This is an amazing question.
Many of us, if sit quietly and think, would get a very very complex answer.

And I am sure that after getting through this question no-one would be able to reply straight away before giving some amount of thought.

For me, success are stepping stones. We always think of something which we want to achieve and once achieved, we think of the next big thing we want.

These thoughts are no more than stepping stones which we need in order to navigate through what is known as Life.

That is my definition of success.
What's yours?
