informative inspiring lighthearted medium-paced

A helpful and highly readable book. It starts with the author’s experiences of overthinking, as well as that of her friends and family. Then it moves into techniques for breaking the cycle. The last section is a little more loosy-goosy - nice things to do for yourself, and setting your personal values to prevent the opportunity to overthink about stuff (e.g. you’re happy to spend money on experiences, even if they’re a bit more expensive). The techniques for breaking an overthinking cycle were probably the most useful to me, but I did like some of the ideas in the last section. 
 
The end took a slight religious turn - more the author’s experience of churchgoing and a couple of quotes from her priest. I had wondered if this book would have an element of religion to it (this would have put me off if I had known), but to be fair, it was short and non-preachy.
