Knowledge comes, but wisdom lingers.
Alfred Lord Tennyson
Learning sleeps and snores in libraries, but wisdom is everywhere, wide awake, on tiptoe.
He who devotes sixteen hours a day to hard study may become at sixty as wise as he thought himself at twenty.
Mary Wilson Little
He who lives by the crystal ball soon learns to eat ground glass.
Edgar R. Fiedler
Do not go where the path may lead, go instead where there is no path and leave a trail.
Ralph Waldo Emerson
