It sounds like you have about the same activity level as I (depending on how much free time I have!). I never have a motivation problem when it comes to getting on the bike, because I love to ride! I look at every chance to ride the bike as a gift to be cherished. Heck, after doing a century on a Sunday, I look forward to the commute on Monday. Who knows what could happen tomorrow? Get out there and ride today!
jyossarian makes some excellent points, too.
(BTW, new boots + much hiking == bad idea)
