It helps, the overall person. Of which "Anger" may be one issue.
"Anger" for some people, being just the way they express, Stress, or "Worry", for example.
"Anger" is the outcome of a person's stress or whatever.
And it is sabotaging, for you and others.
Good book.
Easy to read.
And you will learn about yourself.
My Husband, got me this.
I read it.
It is good.
Good for ANYONE. Negativity or not.
It can help anyone, be successful and to learn better ways of handling themselves. The overall, person.
The book says it helps with "anxiety or depression."
But, I don't have that problem, mine was stress.
So, the book to me, is not about 'anxiety' or 'depression'... but INSTEAD about how to improve the manner, in which you 'react' to things. Hence, Stress and then "anger"... which in your case, is expressed by "yelling."
So that is the way I look at it and how I read the book.
Per how to self-improve. Overall.
And how other very successful people, handle difficulty.
The book, is helpful in learning alternate ways, to handle difficulty.... and how to 'react' in better ways.
No matter how you grew up.
The Author herself, had a very bad childhood. And she talks about how she overcame all those issues, to better herself.
Anyone, can... improve themselves.
But like anything, no book or method will work, unless the person themselves 'wants to' improve.
all the best,
