An alternative to “The Courage To Be Disliked”

I was looking for a self help book to help me deal with a**holes at my job. So I thought I would try reading "The Courage to be Disliked."
Unfortunately, the ENTIRE book is written as dialogue.
I can't read 270 pages of dialogue. I will not abide.

Can someone recommend an alternative self-helpy type book that shares the same message or advice?

Thanks!
