Uh-oh... this list is going to be a lot of "do what I say, not what I actually manage to do..."
1) Keep only one credit card.
2) Pay all your bills on time.
3) Cook your meals ahead of time (I do most of my cooking on Sunday and Monday evenings.)
4) Pack your bag at night.
5) Always put your keys in the same place.
6) Charge up your phone and computer every night, too.
7) Do the dishes before you go to bed.
8) Clean out the fridge a couple times a week, and label all the left-overs clearly.
9) Do the laundry every day, instead of twice a week. (I know this doesn't work for most people but it really helps me out!)
10) Get enough sleep that you can think straight!
