No matter where we live, whatever we do, and whatever the social situation, friends should always be a part of someone's life. This is just the meaning but the meaning changed when the word "difficult friends" was added to the dictionary. The experience of having difficult friends is uncomfortable and makes you feel contracted, defensive and yucky.
This book “Smart Tactics To Influence Difficult Friends With Little Motives Instantly” provided a platform to recognize difficult friends, and explaining in sentence two tactical ways to influence Difficult Friends, what to look out in difficult friends, amongst other valuable explanation in various chapters of the book.  Each type of person needs to be influenced in a specific way. Some friends want to take credit for what you do.
Indeed, the book captured the rudiment of the discussing subject and showing readers’ benefits all over it.
