Why be happy?

Sometimes I am asked why I can be happy while others are going through stressful times. The answer is simple. I hate being stressed and I hate it when others are stressed. Especially when the stress is caused by something beyond that persons control. Adoption process is like that. Lots of things I can't control but if I dwell on them I will go insane. So I choose to be happy. It is a deliberate choice and I make it freely. I try to make that choice often if not everyday. It is the least I can do for myself and those around me.
