To a large degree, the measure of our peace of mind is determined by how much we are able to live in the present moment. Irrespective of what happened yesterday or last year, and what may or may not happen tomorrow, the present moment is where we are always!
Without question, many of us have mastered the neurotic art of spending much of our lives worrying about a variety of things all at once. We allow past problems and future concerns to dominate our present moments, so much so that we end up anxious, frustrated, depressed, and hopeless. On the flip side, we also postpone our gratification, our stated priorities, and our happiness, often convincing ourselves that "someday" will be better than today. Unfortunately, the same mental dynamics that tell us to look toward the future will only repeat themselves so that "someday" never actually arrives. When we're busy making "other plans," our children are busy growing up, the people we love are moving away and dying, our bodies are getting out of shape, and our dreams are slipping away. In short, we miss out on life.
Many of us live as if life were a dress rehearsal for some later date. It isn't. In fact, no one has a guarantee that he or she will be here tomorrow. Now is the only time we have, and the only time that we have any control over. When our attention is in the present moment, we push fear from our minds. Fear is the concern over events that might happen in the future and we don't have enough money, our children will get into trouble, we will get old and die, whatever.
To combat fear, the best strategy is to learn to bring our attention back to the present. Practice keeping our attention on the here and now. Our efforts will pay great dividends. "Let not your heart be troubled: ye believe in God, believe also in me." John 14:1
