What to read...

I have two new books and I am not sure which to read first. One is a gift from a friend, called "Managing Your Emotions - Instead of your Emotions Managing You" and the second is "Anger is a Choice."
I have been deemed an angry person more than once in my life, so is that the emotion I need the most help managing? Or is my anger a symptom of some other deeper rooted emotion? I guess the only way to find out for sure is to read the books, which comes back to the original question, which to read first. (I am not one of those who has several books on the go...)
So it comes back to FEELINGS, and I feel angry more than anything else... I guess that's my answer!
