Why am I so difficult?

I seem to like doing difficult things.

In college, I wrangled with the administration and finally the headmaster to let me take 4 level subjects although it was "discouraged", so people could "focus on getting distinctions for 3 core subjects". It ended up with me having to go for extra classes just so my schedule could fit in that extra course. I didn't get a distinction for it of course, course that "extra" was Physics, and although I liked finding out how things worked, I can't calculate how they work.

In university, I took on extra courses in another faculty, in History and Literature, for the heck of it, even though they didn't give me any extra credits when I graduated. I also took a course which I knew I didn't have the aptitude for, but just so I could stimulate the lacking parts of my brain. I scraped through the course as I knew I would.

When I was working, I stood up for some timid little girl who couldn't stand up for herself, and nearly ended up in a fight with the pervert who was harrassing her. She subsequently withdraw her charges because she was too scared, of course, and I never saw her again after that because she left the company. But then again, I won't be surprised if she continues to draw attention with her "oh please help me" demeanour, and then backing off again because she got more attention than she bargained for.

There are numerous other stories of how I seemed to enjoy making things difficult for myself, and then getting nothing out of it in the process, or even getting into the trouble some of the times, but it hasn't seemed to stop me somehow. I seem to still continue making the decisions to embark on difficult projects.

The next difficult thing I may be doing could be co-working on a project with a certain person whom, to put it mildly, has never been one who is easy to work with, even at the best of times. I do wonder, and wonder often, whether I should even consider something so foolhardy. But at the back of my mind, there seems to be a quiet certainty that I will most probably agree to it, should it start to take off.

And if it does take off, it's going to be a hell of a ride I can assure you.

Somebody tell me why I'm doing this again?
