Darren Hardy is the publisher of Success magazine. I strongly suggest you subscribe to it. Even if you don't actually read the magazine, each issue comes with some awesome audio for you to listen to – great interviews with successful people. If you get the print version, there's a CD bound into each issue. The digital version allows you to download the MP3 files. I listen to these in my car, and find them very inspirational, very motivating.
