Believe
It is important for each of us to believe in something. Whether it is another person, yourself, God, Mother Nature, science, astrology, etc. This is what anchors you to a system of ethics, morals, beliefs, and traditions. Believing in yourself should always be one aspect of your belief system. If that is where it stops, then so be it. The point is that you should seek out in your mind what you believe in, what you trust, what connects you to yourself, to others, to the universe. If it is not apparent to you, then it is a worthwhile exercise to seek your belief and truth system. For some, it has been the same for as long as they can remember, for others it is a changing thing, and for others it is still an open book. Take the time to explore.
