I've absolutely fallen in love with Podcasts. Here's why: I spend a lot of time on the road and I feel like driving is an absolute waste of valuable time. My good friend and I were planning a road trip for the weekend so I scoured the net for some decent podcasts. I've posted my favorites here. The six hour round trip was spent learning about project management and entrepreneurial subject matter. I came home from the trip extremely excited to put some of that knowledge to work. There's so much free information on the web. Apple has a great getting started guide on how to tap into these resources.
If you haven't learned it yet, you'll quickly find that as an entrepreneur your time is a valuable commodity. If you have a passion for learning and you spend a lot of time on the road, I highly recommend using ITunes and your MP3 Player to listen to podcasts while driving.
