Organize your personal space so it works for you. After being around a hectic, chaotic environment, you need quiet, private space, and fill it with things that are meaningful to you. Being positive, not negative, can reduce a lot of stress. Put problems in a broader perspective. Step outside the situation and decide how important the whole thing is.
Exercise is a great way to release tension.
It can lift your spirits, relax you, and increase your energy. Don't skip meals. Your energy level will go down quicker without nutrition. Never think that you haven't got the time. Get enough sleep and rest.
