Don't argue for other people's weaknesses. Don't argue for your own. When you make a mistake, admit it, correct it, and learn from it / immediately. - Stephen Covey

Principles are universal — that is, they transcend culture and geography. They're also timeless, they never change — principles such as fairness, kindness, respect, honesty, integrity, service, contribution. Different cultures may translate these principles into different practices and over time may even totally obscure these principles through the wrongful use of freedom. Nevertheless, they are present. Like the law of gravity, they operate constantly.

Values are social norms — they're personal, emotional, subjective, and arguable. All of us have values. Even criminals have values. The question you must ask yourself is, Are your values based upon principles? In the last analysis, principles are natural laws — they're impersonal, factual, objective and self-evident. Consequences are governed by principles and behavior is governed by values; therefore, value principles!

When you live out of your memory, you focus on the past. When you live out of your imagination, you focus on the future.
