There are some great FREE podcasts to listen to as you're driving home from work, mowing the yard (coming soon!), or drinking coffee at your favorite hangout.
Tack Sharp's episode #1 had this suggestion from pro photographer, James D. Davidson (approximate quote):
"One of the best things for a new photographer to do is bolt on a 50mm 1.8 lens and don't take it off for a long time. You'll learn so much about shooting with that prime lens."
Here are some good websites (in no particular order)--from there you can get FREE subscriptions to their podcasts from iTunes.
