Calendar I use a 12 x 12 calendar with the blocks to record my appointments and events scheduled for the month, then I can see at a glance how much time I will need to schedule to rest before and after the event. This tool is extremely important to me. Earplugs I live on a comer of a busy main street and the noise of the cars going by all day disturbs my peace and sleep, so I use Husher ear plugs when I need rest. They block out most sounds but you can still hear your smoke detector, alarm, etc., in case of emergency. They can be opened when you need light.
Shades are also easier to clean than blinds.
Machine A must if you are too fatigued to get up to talk but don't want to miss a call. The volume of the answering machine can be turned up or down. Phone I turn my phone off when resting. Caller ID is very good if you want to block out people who are annoying, or you get crank calls, or you just want to know the name and number of people calling you. You can also have your number blocked out if you don't want your name and number to show up on the other end.
