In a world where Atomic Habits, did not exist, I’d call Tiny Habits the best book on behavioural change and habit building.
Or maybe, I am biased because I read James Clear’s book first.
Just like Cal Newport took Anders Ericsson’s work and ran with it; so did James build on BJ Fogg’s.

Tiny Habits is lovely, has pretty tables and is a lovely engaging read.
If you want to change your behaviour, you simply cannot go wrong by learning from the man, who has taught many of our modern day influencers like Ramit Sethi or Instagram founder, Mike Kreiger.
