Thanks to having to wake up at five thirty for school and barely being capable of coherent thought, I mastered the ten minute shower. All in all, about fifteen minutes, if I didn't shower the night before.
This is the main reason why I typically don't wear makeup and my hair is usually fixed simply or just brushed and left long. It just became habit to not do these things.
But in all seriousness, it depends if I showered the night before. If not, it might take me roughly twenty minutes. Five to get dressed, five to eat (or five to look for food, if we don't have any), ten minutes to shower, if I know I'm on a schedule.
For work or school, it takes me about half an hour. I spend that entire time not only getting ready, but waking up. Have to make some coffee and get the grumpiness out of my system. =.= And if there's time, I'll lift my weights. Helps me feel strong throughout the day.
Otherwise, it takes forever for me to get out of bed. I'll just lay there until I feel like getting up, masturbate, then lazily reach for my weights, lift them a little, then get dressed and go do stuff. If there is stuff to do...
It depends on how well I slept and why I'm waking up in the first place. If I have class, I'll take my time, have a shower, drink some coffee, and get dressed. Takes about a half hour: ten minutes to get out of bed, fifteen minutes to wake up in the shower, then five to get dressed, brush my teeth, grab my stuff and get out the door.
If I'm in a hurry, no more than five minutes to make coffee to go, shower, brush teeth, and get dressed.
