A reasonable book
It’s an ok book. Short with some good parts to it. There is very little here to do with Stoicism though beyond very sparse high level stoic quotes such as “focus on what you can control and not what you can’t”. Being an avid stoic reader I was actually becoming frustrated towards the end at the lack of stoic practices and philosophies being even mentioned never mind applied.
Being from Addy, this book is naturally aimed at a knowledge worker and like I say has some ok parts but it’s mostly truisms and basic with very little actually actionable points besides “do the work and focus on what you can”. You shouldn’t need a book to tell you this. If you do, there are far better ones to remind you (Cal Newport, etc)
For me, my biggest bug bear is it just had a very misleading title and if you know even the basics of how to look after yourself, prioritise your work and well being then there is little to nothing here for you and you can move on.
