Keep clutter down~when you get your mail, pitch junk, put bills in your bill bin, file what needs to be filed (bank statement, retirement statement), put magazines where you can read it in your free time (sure we have free time); after you read your magazine recycle it. This is so simple in theory, but sometimes it is easier said than done. Some days I do better than others it is a work in progress.
Make a list of what you want to accomplish each day mark off each item you get done. It makes you feel good to see your list go down and all that you did get done. If you have anything that you couldn't get to put it at the top of tomorrow's list.
