When you were born you were crying and everyone else was smiling. Live your life so at the end, your're the one who is smiling and everyone else is crying.
Go on bravely. Do not expect success in a day or a year. Always hold on to the highest. Be steady. Avoid jealousy and selfishness. Be obedient and eternally faithful to the cause of truth, humanity, and your country, and you will move the world.
To each there comes in their lifetime a special moment when they are figuratively tapped on the shoulder and offered the chance to do a very special thing, unique to them and fitted to their talents. What a tragedy if that moment finds them unprepared or unqualified for that which could have been their finest hour.
