Have only as many credit cards you need—one personal, one business. Think of all the time you’ll save when not dealing with more. The only exception would be for a store card or two where you visit at least once a month and get special offers and discounts for using that card.
When preparing meals, do it near the sink to throw peelings into the disposal and put a trash can right next to you for other trash. If you can’t easily move your can, use a bowl to throw stuff in to be emptied later.
Tickler file at home. If you don’t have much going on every month, just make a file folder for each month. Have a calendar in there that shows birthdays and other days you want to send out cards. Put the cards in that folder when you buy them. Stash tickets, invitations, letters you need to answer and anything else that you want to do in a particular month. I do that and keep a Google calendar on my computer for a quick glance to see what’s coming up, like doctor appointments. Using both the file and the calendar, I am usually on top of everything.
Have a box (about shoe-box size) next to where you store your purses. When you want to change bags, put everything into the box and sort through it to arrange the new purse.
