You can only carry this so far. The poor child out on a desert dying of malnutrition is creating nothing but pain and suffering. I would however, certainly call creative the person who finds a way through great difficulty to feed that child. The one thing we seem to agree on is that all people are, in their essence, creators and artists. Whether they have created something yet, or not, is not the issue.
People are creative, period.
Some of us, a small group, agree that we are also a creation, and therefore we are a Work of Art. That is, those of us who accept that there must be a Creator to this artfully created world we live in. The other thing we all agree on is that Life is Art. All life is Art. This is a tough thing, defining creativity.
