IF
IF...you can keep your head when all about you are losing theirs and blaming it on you. If you can trust yourself when all men doubt you, but make allowance for their doubting, too; If you can wait and not be tired by waiting, or being lied about, don't deal in lies, or being hated, don't give way to hating, and yet don't look too good not talk too wise; If you can dream and not make dreams your master, if you can think, and not make thoughts your aim, if you can meet with triumph and disaster, and treat those two impostors just the same; If you can bear to hear the truth you've spoken twisted by knaves to make a trap for fools, or watch the things you gave your life to, broken, and stoop and build 'em up with worn-out tools; If you can make one heap of all your winnings, and risk it on one turn of pitch-and -toss, and lose, and start again at your beginnings, and never breathe a word about your loss: If you can force your heart and nerve and sinew to serve your turn long after they are gone...And, son, hold on when there is nothing in you except the will which says to them: "Hold on!" If you can talk with crowds and keep your virtue, or walk with kings--nor lose the common touch, if neither foe nor loving friends can hurt you, if all men count with you, but none too much; If you can fill the unforgiving minute with sixty-second's worth of distance run, yours is the earth and everything that's in it! And, which is more, you'll be a man, my son!
Rudyard Kipling
You can't bitch your way to productivity.
Will St. John
Men give some credit for genius. All the genius I have lies in this: When I have a subject in hand, I study it profoundly. Day and night it is before me. I explore it in all its bearing. My mind becomes pervaded with it. Then the effort which I make, people are pleased to call the fruit of genius. It is the fruit of labor and thought.
   Alexander Hamilton
The more you do of what you've done, the more you'll have of what you've got.
