Back when I used to work 2 jobs (one 40 hour, one 15 hour) I had to make a home schedule. Make a REASONABLE schedule........
AND stick to it. Maybe Mondays will be dusting and putting away clothes, Tuesdays could be running the sweeper and sorting mail. If you know you are giving yourself 30 minutes, schedule a job or jobs that should take that long and no more. You'll soon find yourself in the habit, and not need a schedule
One thing that helps sooooooooooo much since it's just you (no kids involved) put stuff away to begin with. Have a designated basket for mail..........put it there. If you get something out, put it back. Make things easy and quick to put away. For instance, each of my kids have their own small plastic tote for the bathroom that sits on the shelf. All their toiletries are in it, they can set the basket on the sink, use what they need, toss it back in and put it back on the shelf. I made it easy for them to keep their stuff together and picked up. That makes it easy for me too! LOL
