To a large degree, the measure of our peace of mind is determined by how much we are able to live on the present moment. (31) of what happened yesterday or last year, and what may or may not happen tomorrow, the present moment is where you are—always! Without (32) , many of us have mastered the (33) art of spending much of our lives worrying about a (34) of things—all at once. We allow past problems and future concerns (35) your present moments, so much (36) we end up anxious, frustrated, depressed, and hopeless.

(46) fear, the best strategy is to learn to bring your attention back to (47) . Mark Twain said, "I have been through some terrible things in life, some of which (48) happened." I don’t think I can say it any better. Practice (49) your attention on the here and now. Your effort will (50) great dividends.
