1. Sleeping Pattern - Go to sleep at the same time every night and wake up at the same time every morning. The health benefits to this practice are substantial.
2. Nutrition - Eat the healthiest food you can afford. This might be difficult if you are not in charge of your groceries, but do what you can to make the right choices when it comes to food.
3. Mindset - Don't worry about things you cannot control. Learn to focus on the things that you can control and identify anything that needs to be addressed.
