A Wise Man Once Said:

A wise man once said that the only thing that mattered was the present, the past has happened, you can't change it, and the future is undefinable, it is what you do now that counts. it has been repeated and modified many times, but the original words were; "The clock is running. Make the most of today. Time waits for no man. Yesterday is history. Tomorrow is a mystery. Today is a gift. That's why it is called the present." the author is unknown, but is true nonetheless.
