I read another book about introverts first (Introvert Advantage), but this was definitely my favourite of the two (Introvert Advantage is worth reading as well, but this book felt more relevant to me). I didn't like the cover photo (initially) but it grew on me over time (not that it matters much anyway).
I bought this book because I was struggling to understand why I felt differently to my friends - they wanted to meet up and go out as much as possible, sing and dance etc, whereas I'm happy enjoying my own company, reading, or just doing my own thing. It was really getting to me why I wasn't enjoying all the things everyone else seemed to enjoy. I felt like I didn't fit in. But this book helped me to understand that I'm not weird, I'm an introvert. I would recommend it to anyone who feels like they don't fit in when out socialising, or who feels awkward at parties and wants to go home before everyone else. It helps you to accept the way you are instead of trying to fight it and feeling bad about yourself when you can't fake being an extrovert. It's been therapy for me. I'm glad I'm an introvert and this book helped me realise that.
