A lot of people are saying anger is necessary to get things done. And others on here have said being happy can't change anything.
But I completely agree with you Tynan. When I was younger, I felt like I had no control over my life, and I had no idea what my purpose was....that led to me lashing out at everyone who said anything that I took as an "injustice".....but it wasn't til I turned 17 that I realized justice is in the eye of the beholder and it never helps ANYone to be angry.
You can stand up for yourself and others, while being completely calm. Actually, people tend to listen to you if your calm, than if you're in a blind rage, or even slightly angry.
I believe if everything is right with them...people should be happy 100% of the time. Even if something bad happens! because when happy people are sad, they cry over loved ones lost, but they get over it and are happy again!
