Gaatlok's anger is something that he has struggled to control for many, many years. It has impaired his ability to woo, impress customers, or deal with difficult situations in general. While he may have it in check most of the time, even being somewhat patient with as many people as he can, there is a limit to how much he's able to stomach before exploding. It has, however, directly lead to the training that he has received. His instructor in the clan was impressed with how quickly he jumped to battle against the drake, and taught him a modicum of control, how to focus that rage. Merely focusing the anger does nothing to properly quell it, but chopping firewood has proven to be most therapeutic. Gaatlok is a simple man, of simple tastes, and doesn't let too much thinking get in the way of important decisions. More often than not, he has found that thinking about something too hard only makes the problem worse. Instead, he acts.
