I will naturally heat and cool my house, office, or dorm room by opening or closing my windows, curtains, and blinds, and by using fans.

I will keep lights, electronics, and appliances turned off when not using them.

I will adopt a diet free of refined sugars, which eliminates sweetened beverages, candy, and processed foods.

I will take a 15-minute walk outside each day.

I will eat all of my meals without distractions, e.g., phone, computer, TV, or newspaper.

I will replace 20 minute(s) of screen time per day with other activities.

I will use a reusable bottle and stop purchasing bottled water, saving 3 disposable plastic bottle(s) a day.

I will take a walk each day.
