'Violently Happy'

Sometimes anger can come so quickly it's alarming, I can be thinking about a lovely day ahead and one thought leads to another and like a train wreck my blood is boiling and am seeing red. I recognize this now, but I still don't understand how or why this is the path that comes so easily

Why can't I have a train of thoughts that leaves me giggling like a tiny child on the floor? Or has me figuring out the way to create world peace?
​
Perhaps I'm just not intelligent enough to do that, and I will just have to continue blindly falling my way through my life as per usual (?)

My learning from this is that we shouldn't weight any emotion with more weight than another. No emotion is good or bad, it just is. ​
