Until you think of your bike as the vehicle you take to work, weeks like this will occur. I've had weeks like that in the past. I've just adjusted my mentality that my bike is my mode of transportation. It is now a very rare week that I don't ride my bike to work five days. It took two years to get to that point. If I have to do pickup-and-drop-off of the kids at daycare, I drive the kids with the bike on the rack. Leave the car at daycare and ride to work (reverse in the evening). There are no excuses. Just do it.
