Back in college at Montclair State University, I ended up in this Social Problems in Sports class that I thought would be a nice, interesting "A". It turned out to be a fun class with a good grade, but the professor, Dr. Rob Gilbert, went above and beyond in the classroom. He actually had a phone number on which he recorded an inspirational message every day, so you could call in and get inspired when you were feeling down.
I checked in on it recently and it turns out he has web-ified it, and of course, it's free. If you are looking for inspiration, he's got it on the Internet in daily doses.
And, if you ever go to Montclair, take a class with this man. It will change your life. It changed mine.
