On the computer issue - I like to track mileage for lots of reasons (maintenance) and heartrate (to see how I'm doing, generally). It's often the case that I don't want to see those things on a ride, though - on those days, I put my computer somewhere I can't see it. I forget it's there 'til later, but I still have my data. Works for me, but might not work for everyone (if you're the type of person who couldn't "not look").

Just an idea!

My motivation is lesser right now too. I'm trying to build back up fitness now that my thyroid levels are some better and I feel some better. That's a very long term, discouraging thing to do - exercise just isn't fun right now at the levels I push myself to.
