Unoffendable : The Art of Thriving In A World Full Of Jerks by Einzelganger.
The word Einzelganger means a lone wolf or loner in Dutch/ German. The author has an immensely popular Philosophical YouTube Channel by the same name, and the link to it is posted below
The book is 200 plus pages but each page is filled with wisdom to counter unpleasant situations. It contains a lot of derivations from Stoicism and Buddhism. These concepts are discussed with modern times in mind. It is autobiographical, and the author has brought out some of the most difficult and embarrassing situations he has been in life. Many of us won't dare to talk about these things with our friends, and kudos to the author he has discussed it in the book. The language is simple and the thoughts are expressed crisply. This is not a one time read book but it should be carried as a part of your survival kit. The situations described in this book will keep popping every now and then in our lives, and some of the solutions discussed in the book would assuage our feelings, and alleviate our situation.
I give it a 8/10
