Full little knowest thou that hast not tried, What hell it is in suing long to bide: To loose good dayes, that might be better spent; To waste long nights in pensive discontent; To speed to-day, to be put back to-morrow; To feed on hope, to pine with feare and sorrow.
Geoffrey Chaucer, Edmund Spenser (1874). “The Canterbury Tales and Faerie Queene: With Other Poems of Chaucer and Spenser”, p.598
