Smiling is a big help. You know what? Whenever you smile, your muscles start to relax all over the body. Every single muscle will relax. If you don’t believe it, just try it and you will feel that it is true. With a relaxed body, you feel much better, you can work better, you can even reduce pain in your body. And, believe it or not, you can even change a bad mood into a good mood. Smiling and being angry just don’t go together. And smiling and feeling anxious are also two opposite emotions. So: smile as often as you can. Actually, there is no limit to smiling. So just do it.
