I had a fruitful PM exchange with skinmaan a few minutes ago. I wanted to share something that I learned.
There is a highly-rated, large ebook at Amazon called
Grit: The Power of Passion and Perseverance.
Check your Amazon Kindle library (if necessary) to see if you have it!. The Whispersync audio narration is currently
free. I think that I remember that the Audible audio is $17.95, so the savings is huge (not considering what you spent to get the ebook in the first place).
Unfortunately, I didn't have it in my library. I can't even borrow the title from the public library and get the audio free, with Amazon's/Audible's policy being what it is now. Life is so unfair!
