Nick Hutchison argues that personal development books are vastly underused despite being cheap and quick to read. He quotes Mark Twain: someone who doesn't read good books is no better than someone who can't read at all. The point is simple: pick one up and actually apply what it says.

If you're tired of living under your potential, letting the days pass you by, and just being a sheep, then I encourage you to start reading personal development books. They will help you rise to your potential. I believe personal development books are one of the most underutilized opportunities for growth that we have available to us today. These books are $20 apiece. You can consume them in a few hours of your time, and once implemented, they can change everything. On my bookmarks, I have this Mark Twain quote that reads, the man who does not read good books is no better than the man who can't. You have these books available to you, and if you choose not to read them, you're no better than somebody that can't read in the first place.
