This book is a very funny and honest book about what it’s like to be an over-thinker. From daily tasks to relationships (be it friends or partners) Hayley shows the reader that they are not alone in their intrusive thoughts. The chapters were short and to the point, and I loved that Hayley included dialog from Brain and other characters from her skits on the internet. Some of the middle chapters got a little dry, but then towards the end Hayley bares her soul and shares her grief of losing her dad to a very rare and cruel form of dementia. It was a great book and makes Hayley become more than just a funny internet personality, and instead someone you feel you can get a cup of coffee with and chat about pesky Brain and all the things you overthink about in life.
