What is a perfect act? It harms nobody; it brings at least some benefit to somebody. You can use anything and everything to achieve some good purpose. Keep that in mind as your goal. Whatever you think, whatever you say or do, ask yourself: “Will it harm anybody?” The answer should be, “Absolutely not.” The next point is, “Will it at least benefit somebody?”. The answer should be “Yes”. If it is not benefiting anybody, it is a waste. So, no harm to anybody, at least some benefit to somebody.
