I'm fascinated by the concept behind Charles Duhigg's book "The Power of Habit: Why We Do What We Do in Life and Business," which dives into the reasons we keep doing the same things over and over.
What's illuminating is not only why we fall into habits but Duhigg's insight into business opportunities and advice on how people can break out of those often destructive routines.
If you can't find the time to read Duhigg's book, excellent shortcuts include this NPR "Fresh Air" piece, The New York Times book review and the NYT Book Review podcast, all of which offer rewarding takeaways in fighting human nature.
