Not all education has to be done in the classroom. Especially if it's something you love. I've always been an avid fan of the library but don't have enough time to read all the books I'm interested in. Non-fiction seems to go somewhat slower.
But I'm getting smarter now. I've discovered books on CD. The players can be purchased at Walmart for $10 to $15 dollars.
Most libraries now have the online browsing feature that allows you to pick the subject and then specify CD only. Once you've placed the request you're on your way. You can pick any subject you want, from gardening, to novels, to biology. If you are interested in finance most of the blogs on the left have recommended reading lists to give you some ideas of titles or you could browse Amazon and then see if your library system carries a copy.
It's great! Just choose your subject and you can become an expert in no time!
