Listening vs. Reading
If your the average person then you like to learn something new whenever you can. But reading takes time and effort, however, listening to a book being read to you may seem unproductive for some.
So what do you do?
I personally enjoy both. Though I retain more when I hear the content being read to me because I am an auditory learner. If I were a visual learner then perhaps reading would be the better route for me. Test drive both methods for yourself and see for yourself what enables you to retain and recall the information. There is no right or wrong answer, it's individualized to your brains chemistry and learning style.
