I love reading these books. However, they are never about work or business for me. The books always instruct me to figure out what's important and focus on that. And the books are full of catch phrases and various ways to "be the best".
I've read so many of these books over the years. Each time I read one I stop to think about what's important. And what's important really hasn't changed and it probably never will...that's a sign that it's important.
