I love having things organized. Cleaning or getting things organized is one of my main strategies for combatting stress. Whenever I feel overwhelmed I make a list of all the stuff floating around in my brain. Whenever I feel like things are out of control or I am just not able to concentrate, I clean or straighten up the area around me.
It may make me sound neurotic, but it helps. Even the act of cleaning is cathartic for me and I feel better as I do it. Just another one of my quirks.
