El Tigre from Coyolito

"There have been joys too great to be described in words, and there have been griefs upon which I have dared not to dwell, and with these in mind I must say, climb if you will, but remember that courage and strength are naught without prudence, and that a momentary negligence may destroy the happiness of a lifetime. Do nothing in haste, look well to each step, and from the beginning think what may be the end.
