Something you have to do every single day regardless of what day it is. (Don't mention school or work unless you do that 7 days a week)
The one thing that I must do every single day, walk my dog for 1.5 to 2 hours per day, regardless of weather. It does greatly help that I work from home. She is a very energetic breed and gets very restless unless shes had her daily exercise. Been doing this every day without a break for the past few years, I don't even log into WoW or MMOChampion unless I've done this first since WoW can distract me for hours without me realizing.
What do you every single day of the week? (besides eat sleep n poop)
