Take good care of yourself. Eat properly, get regular rest, keep a routine. Allow yourself to do something you enjoy each day. Paradoxically, the time we need to take care of ourselves the most, when we are stressed, is the time we do it the least. When we feel overwhelmed we tend to eat poorly, sleep less, stop exercising, and generally push ourselves harder. This can tax the immune system and cause us to become ill more easily. If we take good care of ourselves to begin with, we will be better prepared to manage stress and accomplish our tasks in the long run.
