Bah! You're such a pessimist sometimes. Of course, it can be done! You'll not find a soul that can legitimately say I have been anything but cordial in group over the last 3+ years, and although there are various opinions about my capabilities on Eriik, I don't think that anyone who remembers me would deny me from a party because I couldn't fill my role.
Anyway, the point is that there is nothing special about me. I get up in the morning, shower, go to work, go to the gym, come home and game with my family and friends. I get angry, and I get frustrated just like everyone else, but how we behave in those situations can be controlled. Admittedly, I do it better in game than on the forums or in RL. Still, the bottom line is that if I can do it when DDOing, most should be able to. It just maybe takes desire and commitment, but hey, most things worth doing or having take the same.
Cheers,
E.
PS: There are so many things that people don't do that they could if they just decided to. The difference between outcomes is often just a matter of choice and the determination to follow the course.
