anything constructive is constructive… 
messing about on the internet all day, eating chocolate fudge brownies for breakfast at 4pm, and procrastinating for 6 years over employment and education options- that sort of thing (aka: my lifestyle generally) is rather unconstructive.
i have a place for everything, and everything is always in its place. the places tend to be clumps and stacks, and the everythings are paperwork and sewing materials on the bed, dirty laundry on the floor, clean laundry slowly festering in the machine or on the floor next to it, or piled inside the closet that i can’t frigging see inside of cos it’s dark, dirty dishes live all over the kitchen topsurface and stacked in the office, flyers and mail and newspapers live on the coffeetable, floor, and stairs, catfur tumbleweeds are generally spilling gracefully down the stairs and forming new colonies as the air and foot-traffic rolls them around gently, etc….
