1) I shower the night before
2) Make my lunch \ breakfast \ snacks
3) Organize my gear. Fairly easy since I have a closet with my cycling gear in it.
4) During the warmer months that I am using lights I put them on my bike the night before.

I do not shower or shave at work. This is done when getting ready in the morning.
I can get out the door in 15 minutes but tend to lounge around the house while drinking tea and eating my cereal. Getting ones morning activity out of the way helps avoid issues involving a port-a-poti while riding.

I find trying to get out the house as fast as possible in the morning a stressful way to start the day.
