RicardoJM, I like your idea about setting the goal of riding all the way from home at least once per month. My commute from home to work is 32 miles (64 miles round trip). I've done it before, it just takes some extra planning (i.e. going to bed early the night before, getting up early for the 2h20m ride, then leave work at a respectable time (I tend to stay until 6-ish).
I think I'll make this a New Year's resolution!
