Interesting ideas but most of his suggestions are really hard to implement unless you can create your own work/school schedule. It also got repetitive enough as it went on that I just skimmed the last chapters. If you can find a summary of the book, I'd read that instead.

Entertaining and partly even make sense. Quite agree that chronotypes change while we are aging. According to the book, now I'm a bear, but with certain traits of a wolf. But in 10 years' time, I have real chances to become a lion or even God forbid a dolphin. It seems for me, the four described chronotypes don't exist in pure form, only if as an exception.

There was some phrasing of things I wasn’t super keen on and I’m not too big a fan of the implication that everything can be fixed by following a regular schedule for sleeping/eating/exercise etc., but I have been following the sleep/wake times for my chronotype and I have been seeing a difference! So the basic ideas, I am a fan of.

Oof. What a disappointment! I really wanted to like this book, but the problems started in chapter one.

In this book, Breus uses the latest scientific studies to revamp the old chronotypes of early bird/lark and night owl in favor of four categories (dolphin, lion, bear, and wolf). Sounds good, but then I take the test and things get confusing. The test says I’m a dolphin, but chapter after chapter I realize that doesn’t always fit. If you fit into one of the chronotypes, you could probably get some good bio-hack tips. But if you don’t, look elsewhere. I did enjoy Satchin Panda’s book The Circadian Code.

Pre-eminent chronotype text.

Very interesting read. I learned a lot about myself and others in my family. It’s really opened my eyes towards habits and patterns the other members of my family do that annoy me. I am a lion in a family with three wolves, so I am the oddball when it comes to staying up late and productivity. Now with this understanding, we are able to work around each other’s clocks.
