Atomic Habits

The book is clear and pragmatic about it's approach to habit formation. It explains each step, and gives good examples on how to apply in your life, while recognizing reality and challenges we all face.

If you are only going to read one, I would recommend Atomic Habits over Charles Duhigg's Power of Habits. If you are going to read both, read Duhigg's first and then this book, the author wrote it and mentions the earlier book.

Like many self help books, this could be an article and just as usefully make all the points. I've found what was said to be true to my learning about creating and keeping productive habits. So it is useful if this is what you are trying to do - or at least would be to someone like me. I think you can probably generally just skim, dive into interesting parts, and read chapter summaries to save time.
