The secret of happy, successful living lies in doing what needs to be done now, and not worrying about the past and the future. We cannot go back into the past and reshape it nor can we anticipate everything that may happen in the future. There is but one moment of time over which we have some conscious control and that is the present. This truth has been recognized not only by the Buddha but also by all the great thinkers of the world. They saw that it is futile to live in memories of the past and in dreams of the future, neglecting the present moment and its opportunities.
Time moves on.
Let us not stand idly by and see our hopes for success turn into memories of failure. It lies in our power to build today something that will endure through many tomorrows, something more solid than castles in the air. The Buddha has shown us the way. The time is now and the choice is ours. Many people just worry by thinking about their future.
