Really, five minutes isn't very much time out of your day, even out of the last hour before bed. You can knock something off the needs-doing list without even really noticing the impact and it's amost as if someone else flew in and made it happen.
Don't plan it. Don't think about it hard. Just suddenly turn into the five minute fairy every now and then and whisk away some annoyance from tomorrow.
Good tasks for these sudden flurries of activity: carrying out the trash, rounding up the dirty dishes from around the house & putting them in the sink, readying something to mail, washing a batch of those dishes, picking up the clothes from the bedroom floor, putting the shoes & coats back where they belong, laying out clothes for tomorrow, dusting a room, cleaning the toothpaste spots off the bathroom mirror, taking the extra junk out of your purse or backpack that you really don't need to tote around for another day.
