How long has it been since you have had a good laugh? I mean the kind where the tears come rolling down your cheeks, and you just can't quit. Doesn't that feel great? They say laughter is the best medicine.
I definitely think we take ourselves too seriously at times. After all, the world doesn't revolve around me nor does it revolve around you. And how boring would it be if it did?!
Sometimes if you didn't laugh, you would cry. I much prefer laughing. Why don't you give yourself permission to have a light-hearted day. Watch a funny movie or look at some Gary Larson funnies. Have fun with some practical joking. Most of all, laugh at yourself. People love to be around other people who are happy and fun - people who smile and laugh. And guess what? You can't be laughing and feeling sorry for yourself all at the same time.
