I should listen to more - but I find that I read a lot, and when I am reading I cant listen to anything and retain it... so it limits my ability to listen to podcasts.

My mind wanders too much when I only listen to a podcast and am not really doing anything else so I get distracted. I find that I can listen to someone speak and retain what they are saying when I can see them speak - but just hearing them seems to go in one ear out the other. I hate it - but its just how I function.
