Ketinggian yang dicapai dan dijaga oleh orang-orang hebat tidak dicapai dengan penerbangan mendadak, tetapi mereka, sementara rekan-rekan mereka tidur, bekerja keras di malam hari. Asli: 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.

— Kata-kata Bijak dari Henry Wadsworth Longfellow
