Keep A Donation Box Ready
Instead of waiting for a big burst of energy to go through all your items, simply keep a donation box in a closet and throw items in as you come across them in your daily cleaning.

While much-loved books like the Life Changing Magic of Tidying Up argue for mass overhauls, you'd be surprised how many things you'll part with when it becomes part of your routine, especially since kids are constantly growing out of clothing and toys.

Already, I have three big boxes to donate without feeling like I made a concerted effort. Although I'm still a fan of digging through closets from time-to-time, it's really the stuff that's out and in my face that drives me crazy, so it's nice to get rid of some of it on a regular basis.
