In your personal life, rather than expecting people to do something for you, ask yourself what can you do for them. In your professional life, rather than expecting your employer to do something for you, ask yourself what you can do for your employer. You will double your success in all areas of life by asking yourself what you can do for others. The most thoroughly wasted of all days is that on which one has not laughed. One of the keys to happiness is the ability to not only laugh at life, but to be able to laugh at yourself.
Laughter releases tension and eases stress.
You always feel better when you laugh. Just think of how you feel when you hear someone else laughing. Some people have such an infectious laugh that they actually make you smile in spite of yourself.
