Why study Psychology?

Why Psychology? This is a question i still hear every time someone asks what I'm studying... Some of my course mates have great ambitions... which is to make the world a better place with Psychology!!! :S
I'm not an ambitious person, so why did i choose to study Psychology in the first place? It's because i have no other choices... Sciences, Business, Designing etc. is totally not my cup of tea, so I'm left with social sciences... and guess what, I'm surely not suitable for Mass Comm, so i have chosen Psychology. Not to say that I'm forced to study it, somehow it is also my interest... I wish to understand myself more, and other people too. And so far i wasn't disappointed...
James' class was interesting, besides his informative lectures, he gave us personality tests too, to better understand ourselves and our classmates. We did another one today, and this is the result of the test i did:

Full of enthusiasms and loyalties but seldom talk of these until people know them well. Care about learning, ideas, language, and independent projects of their own. Tend to undertake too much, then somehow get it done. Friendly, but often too absorbed in what they are doing to be sociable. Little concerned with possessions or physical surroundings.

Accuracy: 99%
Don't know how to end this post... that's all i have to say....
Pheromones are giving me problems! ><'''
