Haven't you always remembered the fairytales heard with a peaceful mind when you were a kid? Try to apply the trick now. Read out the content you are willing to learn in a playback device. Try to put the emphasis on the right words just like the fairytales you heard. Once you are done with that START listening to your recordings before going to the bed with a peaceful mind. Do not try to listen more than half an hour. Repeat the same trick after getting up in the early morning. This would help you remember things better and help you visualize what you have read and you learn things faster and much better.
Hope it helps you. All the best.
