It's about rejecting the default career path which our society considers normal and desirable. The default path is the one where you go to school, enter a career, work the career until you retire ... etc.

I have been a lot of trouble lately figuring out why I'm so unhappy with my career. I knew I was on the wrong path, but I couldn't see the next step on my trail in life. This book made me see that there are plenty of people living happily off the default path. The books made me more determined to seek the pathless path.

I suggest reading it for anyone who is feeling listless in their career and needs a fresh new perspective.
