How will you observe yom kippur?

will you go all out i.e.: no leather, no makeup, no brushing teeth, no washing hands, no shower, no looking in mirrors, no music, and of course no food or water? how many of these things will you observe?

i personally plan to go to kol nidrei on wednesday night, sleep the next day so i dont have to worry about anything until 2:30, and then i have 5 hours left. im taking time off school.
