The very best thing that you can do for yourself is to eat, drink and rest to your health!
Stress is easily brought on by not eating and drinking properly. When you don't get the number of hours of sleep that you need each night, you are only setting yourself up for additional stress.
Limit the amount of salt, sugar, caffeine and alcohol in your diet. Drink plenty of pure water each day and do at least moderate exercise each day. This will breathe new life into your skin, hair and will nourish all of your vital organs.
Breathe properly! Take deep belly breathes to send pure oxygen to all of your body. Laugh and then laugh some more. It is food for the soul! Do the things that please you most. Engage in healthy and fulfilling relationships and work on problems that would erode the closeness that you have with someone special.
