Mood more or less affects whether I ride... once on a ride, I always feel good and love the fact I'm out on a bike but sometimes getting there is a problem. Many things like bad day at work, stress, chores, physical health will affect whether or not I can drag myself out to the garage and onto my bike. I sortof have to psych myself up at work so once I get home I'm ready to change clothes, grab my gear and go ride. One reason why I enjoy group rides, it's incentive to get my act together.
