I wouldn't say I'm very stubborn. I tend to just roll with stuff and I'm happy enough if other people want to do stuff I might not be 100% behind to go along with it anyway. Being stubborn has usually just resulted in me clinging onto being wrong, or drags me into stupid debates in EoEO.

Then again there was that time my math teacher was wrong and I was right, and I was too stubborn to cave and eventually I demonstrated to the class and then to her why I was correct. Took like 20 minutes of arguing though.

I am principled though, and I will try to do what I think is right with as much strength as I can muster.
