I've been a bit lazy since I moved, using any number of arguments to justify not biking to BART in the mornings, despite the fact that it's only a 15-20 min ride. Now I've put myself in a place where I have to ride, hopefully it'll stick and I'll keep doing it at least a few days a week.
What I did was wait until late in the afternoon on Sat to take my truck in for the smog test (to get re-licensed in CA) and service that it needs. I also declined the free loaner that the dealer wanted to give me. That ensured that I wouldn't have my truck on Monday morning and the only way to get work is by bike.
Let's see if it works.
