Hmmm. Good advice for the average Jo Blo that just wants to exist as part of the sheeple. Not so good for business, athletes, some musicians, artists, movie makers or the military. In addition, anger and aggression are natural traits in the animal kingdom and more so in males. How else did we survive and protect the weak in society? Controlling anger is the key, not demonising it. Look up 'Team America Gary Puke Scene' for suitable reaction to unrealistic and idealistic concepts such as this. Haha. Humanity is going off the rails big time.
