What is Life ?

This was a question which came during our last trek ( means my first trek, hopefully not the last one ).

The question was posed to me first, I passed :)

First guy: Life is a reflection of good and bad memories, and the goal is to have more good memories.

Second guy: Is about time and priorities. Very less time, and lots of interesting things to do. Only time is constraint. Make best use of the time.

Third guy: Learn from past, and live life to the fullest.

For me - Perception of life is different each moment... some times i think as a saint, some times as a victim, sometimes as a hero.... I dont have a clear answer... But i do want to explore life more.........
