I track my miles too. Old fashioned way... on a calender. I love figuring out how much I saved in gas, etc and I love seeing the weight come off!
Ok, my suggestions.... take the time to plan out some routes. I do this with ridewithgps.com. Make like 3-5 routes you can pick from and perhaps have a coffee place in there somewhere to ride to. I think working from home and being able to ride is exciting! Just dont get lazy about it.
