Take some time to exercise some consciousness about your body. Really, if it helps you, get to a mirror, and look over your body. Examine what you see.
Run your fingers through your hair. Do the follicles seem healthy? Is there too much grease build-up for your liking? In your experience, what makes you feel better about the hair? Bathing and using a good shampoo and conditioner.
After you bathe and fully dry your hair, compare how you felt before with how you feel afterward. Clean hair has greater volume, feels lighter, and provides better insulation. It feels better to run your fingers through. Try to remember that this is a thing that helps you feel better.
Get to know your gums. They ought to be a soft pink, but just remember what color they are when they are healthy. When you clean them regularly, they stay that nice soft pink color, and they don't develop any redness. Take note of the fact that they feel slightly itchy if you don't brush or floss for a couple of days, and they start looking a slightly more "inflamed" color in places. Paying attention to these details helps you remember to brush.
Spend some time getting to know your refrigerator. Stand in the door for a few minutes, taking care not to leave it open long enough to let in too much heat (I would say five minutes, and close), and take some time to take an inventory of what is in there. Think about what you are going to do with what is in there, and think about what you would need to have the meals that you have in mind. Compare the types of foods you have swirling around in your mind to what you see in the refrigerator, and think about how nice the shelves would look with the stuff you don't need OUT and the stuff you need IN.
The trick I am suggesting comes down to developing familiarity and friendly relations with things in your environment...and with your body.
Leaving the house ought to work the same. Find a small grocer or convenience store near you, and just get to know the manager. Develop ongoing relations. Try to talk about your situation, and try to familiarize yourself with who is going to be there and when. Even if it's just some poor quality gas station a couple of blocks from you, it gives you access to food and contact with somebody who is aware of your situation.
