Nothing huge, lots of little things.

I rode home one night in 16 degree weather. After that, it became much harder to convince myself to take the bus instead of riding. That, in turn, made me strong enough that I get to and from work faster on my bike than on the bus every time. That ride also made me add emergency bus fare to my repair kit.

I have the choice to use the MUP or city streets to get in and out of downtown. One night I rode home on the streets. I saw cop cars scattered around for a few blocks, and a person on the ground who appeared hurt, with the cops shinig their lights on him from a distance and no ambulance in sight. I turned tail and sat in a restaurant for a bit until everything blew over. That made me realize the street route goes through some unsafe areas, and now I avoid that street at night.

Forgetting my keys at work has led me to locking my bike even though it's secure in the garage at work... if I need my keys to leave, I won't forget them in my locker.
