I am a voracious listener of audio books. I listen to them in the car, exercising, on airplanes, in cabs, doing task around the house, and even at the dentist. My Audible account is a true indulgence, and friends know that the ideal gift for me is to send an interesting CD or to e-mail a choice MP3 file.

What I love about audio books is that they help me fill time that would otherwise be wasted. I love to multitask, and listening to a book makes makes even the most prosaic activity more interesting. Audio books make me feel like I am making my life richer and fuller and getting smarter as I stuff my brain with all sorts of stuff.

And I contend that audio books are essential for the well-rounded entrepreneur. In business, there is never enough time to do all the things one wants to do. There is a massive amount of reading to get through--from trade publications to figuring out various new technologies--with the predictable result that recreational reading of fiction or non-fiction often falls by the wayside. Audio books fix that problem and keeps a person literate while also maximizing junk time.

Several people to whom I have suggested audio books have told me they find that it takes some time to get used to listening to one thing while trying to do something else. With practice, however, they have discovered they love audio books as much as I do. Give it a try.
