L. Ron Hubbard -- helping others lead better lives

The Church of Scientology of San Diego shares the following:

"There are only two tests of a life well-lived, L. Ron Hubbard once remarked. Did one do as one intended? And were people glad one lived?"

I think this can be used almost like a "golden rule." If you were to work out what it would take for your to score well on both of these points, and then really stick to the plan, I think that would take care of most of the other issues in life.
