Pick one thing to change that makes a big difference in your life.
Maybe you start a log of important telephone calls in your planner or in a computer log like this one in OneNote.
Next time they claim you never called them, you have evidence.
Or start defrosting meat the night before.
Put out a basket as a designated area for your purse and planner.
My one thing?
When I take off my jeans, I'm hanging them back in the closet. It saves me the trouble of washing, drying, and hanging again. Don't worry...I spill coffee often enough, and therefore HAVE to clean them, that they never get dingy.
