If you don't listen to audiobooks and you're really trying to learn up, I recommend you pick up the habit. It's a great way to keep "reading" while doing other activities, giving your eyes a rest, or if you learn better by listening (you should know what kind of learning is best for you). Also, listening to certain authors can be largely beneficial in picking up their mannerisms, and as a result, their skills. Pitch Anything by Oren Klaff and The Power of Now by Eckhart Tolle are great examples of this and I highly recommend both books.

Money Saving Tip: Amazon has a service called Audible. If you sign up you get the first month free trial you get two audiobooks of you choosing. If you decide you like it, don't keep your subscription normally, go to cancel your membership. When they ask for a reason just say it's too expensive and they will offer you the first three months 50% off and then take it.

Happy listening.
