A few weeks ago I was introduced to the idea of listening to past BYU Devotionals and Forums and I have been listening and listening since that time.

You can browse by topic or search for a keyword. It is nice to have some other listening options during the day. Also, these are longer than a conference talk so speakers can get deeper into topics.
I will admit that while attending BYU I didn't appreciate the Devotional/Forum experience as much as I should have; I didn't think about what a rare and wonderful opportunity it was to listen to prophets, apostles, and scholars speak. Hindsight is 20/20. Now I can't believe that twice a week for years I napped, studied, ate, or sometimes, when attending a devotional, sat distracted and bored instead of appreciating what a gem (for free, mind you) was right at my fingertips.
Lucky for me I can go online and, with much more interest and some more maturity, listen to all the talks I previously rejected. Hooray for technology.
And do not forget to try programs on the Mormon Channel, if you haven't. My favorite programs are Gospel Solutions For Families and Conversations
