1. Make my bed everyday.
2. Make a list of daily "to-do" things and cross them off as I do them.
3. Answer voice mails, e-mails ASAP, then delete them.
Such simple and basic things. The making the bed thing is a minor one, but it is nice to crawl into a made bed at night.
The list is so very helpful. Not only do I forget less, but I accomplish more and feel a sense of accomplishment. I am a geek and carry around a clipboard. But, it is big enough that I don't lose it, can add to it as needed and it is cheap, easy and helpful.
The last one is the hardest, but what a difference it makes to respond to things and then move on to other things.
Simple, but effective
