My questions to life....

Generally, I consider myself to be a very clear person. When I have an opinion, it is in most cases unambiguous and precise, at least to me. Many a times that is to an extent that I come across to some people as a hard headed individual. However, there are a lot of questions that often cross my mind for whom I don't have any answer. I would consider myself fortunate if by the end of my life I am able to gain a better understanding of those subjects. From now on, I will periodically document those questions on this blog. I will be extremely happy and thankful to recieve feedback from people if they have anything to say about them.
Here comes the question for today...rather the description of the question. Most people that I know have something or the other that makes them go crazy. They have a passion for something, maybe a sport, an actor, material well being, books, or something as simple as stamps. The proximity to that one thing makes them happier than the most happy person, and the loss of that can even make them sob like a child. I on the contrary have no such interest. I have not yet come across anything that makes me ecstatic, that would cause an outburst of emotions by me. Often times I consider that to be a virtue, because it helps me be calm and composed when people are going berserk and the need of the hour is presence of mind. But then at others, that quality proves to be bane since I don't find myself agressive enough. When I see a person jumping with joy, I question myself as to should I consider myself fortunate to not have any external factor that can control my emotions, or am I missing the bliss of sheer excitement? On the one hand I see that as people grow older and wiser, they tend to become more unattached and lose that fervor, and on the other I think that maybe the lost of fire made them old!! I have yet not been able to say for sure as to which of these contradicting qualities can be (or should they ever be!!) adjudicated as superior than the other?
