Each of us already operates based on some principles. But none of us gives a second thought to whether those principles are correct or if we are really consistent with them. We may talk about one thing and do another. That would be the worst.

Think for yourself to decide:
What do you want?
What is true?
What should you do to achieve #1 in light of #2?
