For me, the fact that I got on the bike in the spring this year, unlike the last couple of years, has motivated me to ride even more. My goal is 1,000 miles this year (which I am beginning to think is too low), but I am a casual rider, and don't really care about speed or high miles.

If I do the mileage I want for a year or two, I think I might have to look somewhere else for the motivation... I am not sure what that will be, but I suspect that I would shift my focus more toward events or destinations, and making sure I had the miles behind me to be able to enjoy them as much as possible. For me, it might be to ride a section of a specific rail trail, or take a historic or scenic day tour. For you it might be to go out west and ride the RAMROD (Ride Around Mount Ranier in One Day) or another challenging ride.

I also find that having someone to ride with helps me... even though I am an introvert, it is nice to have someone to chat with along the way. I heard something in a movie recently that I think applies at some level, "Happiness is only real if it is shared."

So, the summary of all of the babbling up to now... Don't seek the enthusiasm... seek something to fuel the enthusiasm, and it will happen.
