This was pretty solid. Sometimes with books that are written by a pastor or cleric of some kind, there is a tendency to delve so much into the spiritual side that it feels like a sermon as opposed to a non-fiction, self-help, motivational book. This one does not do that at all.
Keller is a fun writer with some cool and humorous anecdotal stories sprinkled in. It makes for an enjoyable experience. He jumps right into it when talking about successful people, and he defines success beyond just financial success, the "Key" is to remain teachable. He coins the word, "teachability" as a characteristic and trait to always being open to learning, regardless of the situation. This doesn't mean you void all of your prior beliefs.
Often, we only want to learn from someone more experienced that us. Well, he shows that misses so many opportunities to grow. Don't look at it as a hierarchal system. We can (and do) learn from everyone, if we just pay attention and get our biases out of our own way. I've never thought "teachability" to be a bad thing, but this book demystifies the term and explains how to develop this trait and apply it for a lifetime.
The first thing for all of us to do is be deliberate and cognizant of any teachability/learning opportunities. I feel that most hurdles are our own doing with our ego. Once we recognize we ourselves have great insight, and so do many others, you don't feel insecure of asking anyone to further explain something.
Another section I really liked was nearing the end, he discusses how to seek out opportunities from people we want to learn from and ask questions. Even better yet, he discusses being always mentally prepared to ask open ended questions so you don't miss an opportunity during any chance encounter. Pretty cool stuff. Just think of all the things you want to know better, or learn more about, and prep who may know more, and prep questions. Make it a habit, and you really have something!
I did this as an audio book, and it will be one I'm on the lookout for at discount retailer to own and re-read. Give this a try.
