You must live in the present, launch yourself on every wave, find your eternity in each moment. Fools stand on their island opportunities and look toward another land. There is no other land, there is no other life but this.
Henry David Thoreau

Your past is important but it is not nearly as important to your present as the way you see your future
Tony Campolo

Give the present your attention. Focus your conscious mind on the present moment. You can not change the past, but you can change what the past means by what you think and do today. The future is not here, but is created by what you do and think today. So take care and be aware that you are making the most of the moment you are in right now.
