Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less. The truth is you don't know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed. Life is a dream for the wise, a game for the fool, a comedy for the rich, a tragedy for the poor.
