There is nothing like accomplishing the forever-repeating chore of laundry. It is one goal you can always count on completing. There isn't a choice not to. Well I guess you could replace the shirts and socks instead of washing them. But that's not financially possible or prudent. So every week the task is the same, but so is the satisfaction that accompanies it.
A pile of clean clothes is a signal of a start of a new week, and a fresh start to other goals that have yet to be tackled.
