Morning: pack backpack with clothes/breakfast/cell/etc, shower/dress, give bike a once-over, connect headlight battery, inflate tires (once every 3 to 4 days), lube chain (once a week), ride.

Afternoon: change into riding clothes, give bike a once-over, ride.

Periodically: check/refill: wipes, body spray, tubes, etc. Make sure emergancy skull cap, gloves, tools, money, etc are in backpack.

I guess the only "ritual" that I engae in is to ride the exact same route to work in the morning then, change it up in the afternoon depending on wind direction/conditions, etc. I also spend the first mile or two just warming up then, I'll crank it up depending on how I feel.
