The heights by great men ...

The heights by great men reached and kept were not attained by sudden flight, but they, while their companions slept, were toiling upward in the night.

Quotes from the same author

Perseverance is a great element of success. If you only knock long enough and loud enough at the gate, you are sure to wake up somebody.
He that respects himself is safe from others; he wears a coat of mail that none can pierce.
Magnificent autumn! He comes not like a pilgrim, clad in russet weeds; not like a hermit, clad in gray; but like a warrior with the stain of blood in his brazen mail.
For in the night, unseen, a single warrior, In sombre harness mailed, Dreaded of man, and surnamed the Destroyer, The rampart wall has scaled. He passed into the chamber of the sleeper, The dark and silent room, And as he entered, darker grew, and deeper, The silence and the gloom.
Thus, seamed with many scars Bursting these prison bars, Up to its native stars My soul ascended! There from the flowing bowl Deep drinks the warrior's soul, Skoal! to the Northland! skoal! Thus the tale ended.
