My Aunt Ailiin, from Finland, would just tell me to be happy. Today, I will be happy. This is rather a "Riddle me this." write and an interesting one at that!
While we may ask the question a million times, there really is only one true answer, and each of us finds that within ourselves if we are lucky. I like your approach in this poem: it gets one thinking. It rings simple and true.
