Passion - the Agony and the Ecstasy

Many of us have been asked "What is your passion?" and many of us upon consideration, may reply "I don't know." Or maybe reply "Teaching, selling, research, painting, cars, women, ...."

Of course, in the course of growing up, out of necessity of being useful, we discover and develop more of our competencies. We follow the path of security. The subject of passion later catches on and we suddenly feel the need to be passionate but don't know what our passions are.

But the first question may be what is passion? Is it interest, is it enjoyment, something that gives us good feel, makes us tick, we are not tired from it, energized by it?

Today I was confessing to a friend I don't know what my passsion is. I don't know what I like.

And my friend explains that Passion is not just enjoyment, feel good, interest, likings.
He said the word Passion also carries the meaning of suffering, something I am willing to suffer for and to die for.

Passion - the whole experience of the agony and the ecstasy, the steadfastness in the conviction, to the point of laying down one's life for it.

I guess I lack not passion, but the courage of laying down my life, of going through the whole experience of agony and ecstasy.

(The nearest I can think of for most is MONEY.)
