There are many good books you could read about how to get better at life. Jordan Peterson’s works are often recommended. James Clears’ Atomic Habits is helpful. Of course, I’m partial to my own book and highly recommend it from (mostly) pure motives.
But there is another work I recently rediscovered that deserves to be better known and (more importantly) more widely read. Henry Hazlitt is known as an advocate of free-market policies (or maybe non-policies would be a more accurate term). But, thanks to the Mises Institute some of his lesser known works are also available, including his The Way to Will-Power.
They sell the paperback for under eight bucks last I checked. What is more, the offer a pdf version and an epub version for free! If you use Kindle, there is software that will convert an epub file to mobi. Or else you can download it for Kindle at Archive.org, though I can’t vouch for the quality. There is a kindle version for sale at Amazon too.
But the best aspect of the free book is that the audio is also available for free at LiviVox.org. Unlike many free audiobooks, the reader for this one is excellent! If you have a podcast app on your phone you can probably find the book and listen to it effortlessly.
I don’t have any reason to think Hazlitt is a Christian, but the book is still very helpful. I have read or listened to it several times and plan to do it several more. Highly recommended!
