Compulsive habits I've outgrown:

• catch seven drops of water from the showerhead after bathing
• count every stair and skip one if necessary to maintain an odd number of steps
• keep a written log in my nightstand to evenly distribute bed-sharing rights to each stuffed animal

On-going quirks:

• eat seven French fries with a fast food meal
• organize sock drawer, closet, and bookshelves by color
• straighten pictures, notes, pens, staples, magnets, books, etc.
• count to eight over and over again to overcome anxiety in public restrooms
• wash my hands three times every hour

That last one is a lie. I plan to add to this over time.
