Let's face it, with adequate motivation, we'd all be super-buff specimens of physical fitness, ready for any any riding, running, weightlifting or swimming challenge that came along. Since most of us don't fit that description, you can figure most people suffer from lack of motivation to SOME extent.

Personally, I took up bicycling because it was a fun way to exercise, and I hated jogging. As incredible as it seems, there ARE people that enjoy running and have no interest in bicycling. I think the lesson is not to force yourself to do something that you don't want to do, but rather to find fun stuff to do that benefits you. Maybe that's cycling. Or maybe it isn't. But sitting on the sofa eating Cheetos sure isn't it.

Consider changing your cycling up. If you approach it like an exercise routine, leave your heart rate monitor at home and just go ride and have fun. If that's what you're already doing, then take it the other direction and start seriously "training". Take a camera and take pictures. Ride with other people. Drive somewhere new and ride there- try the next state over, see what it's like to ride there. Explore new areas. If you wonder "Where does that road go anyway?", turn down it and see. Seek out a bike rally or two. Jog one day and ride the next. Ride your old bike part of the time. Log your miles on bikejournal.com, see how many you can rack up this year.

Assuming you're up there near the north pole, take up snowshoeing or cross-country skiing in the winter, whatever it takes to get you out of doors. Or get one of those fat-tire snow bikes.
