For the rest of my life there are two days that will never again trouble me. The first day is yesterday with all its blunders and tears, follies and defeats. Yesterday has passed away, beyond my control forever. The other day is tomorrow with all its pitfalls and threats, its dangers and mystery. Until the sun rises again I have no stake in tomorrow, for it is still unborn.
