I loved these lines from a book I was reading:
Time exists in three levels...past, present and future. Learn to balance life. Don't be too past oriented or future oriented. Learn from the past, plan for the future but live and enjoy the present. When your mind dominates your life, then you are either in the past or in the future. Make a decision and see the joy of living in the present. But don't forget to plan for the future or learn from the past.
