I've got my work cut out for me

I was looking at my cached copy of unread mp3-encoded audio books, thinking I should finish reading these before I acquire many more.

I figured I could work that out in a couple of months, but decided to do the math. I have 756 hours of audio and 90-minutes of driving time each workday to listen - but I use some of that time for phone calls.

756 hours distributed over 1 hour/day, 5 days/week, gives me over 2.9 years of audio to cover before my cache is empty! That's pretty wild. I wonder how many new books that I'll want to read will be released in the next 3 years while I'm catching up.
