Here you will find the Poem Another of poet Johann Wolfgang von Goethe
Go! obedient to my call, Turn to profit thy young days, Wiser make betimes thy breast In Fate's balance as it sways, Seldom is the cock at rest; Thou must either mount, or fall, Thou must either rule and win, Or submissively give in, Triumph, or else yield to clamour: Be the anvil or the hammer.
