We mean well when we seek resources to improve ourselves. However, the self-help genre has become something of an obsession, encouraging people to remain in a perpetual state of self-improvement. In a post COVID society, this genre has exploited knowing that people are spending more time at home.
There has been one book, with a chokehold on The NY Times bestseller list, Atomic Habits. It has spent 152 weeks on the NYT bestseller list. Normally, I don’t succumb to the hype, but for the sake of my future self, I did in this instance. 
Atomic Habits is a five hour, audiobook, narrated by the author, James Clear that starts with his personal journey of learning the benefits of habitual behavior. This book started off strong and engaging, however, there is not enough here to recommend it. The idea of forming good habits–that can lead to a fulfilling life–is a profound one initially, until the author uses repetitive rhetoric to stretch a three-page, blog post into a published book.
James Clear talks about how he started this idea–as a blog–that became so popular he was offered a publishing contract. I am not familiar with the blog, but you might want to check that out [if it is still available] before you spend your money on this book.
Atomic Habits is not a complete waste of your time; there are stories about athletes and prominent figures that are fascinating to read. However, around the thirty percent mark, learning how habitual behavior can be a life-changing event, becomes a dull way to spend five hours.
I borrowed this audiobook from my library so, no money lost and no one got hurt. I strongly urge you to do the same before wasting money that could have gone to your favorite latte or deli sandwich.
