William Shakespeare said this quote
“ What if it tempt you toward the flood, my lord?Or to the dreadful summit of the cliffThat beetles o'er his base into the sea,And there assume some other horrible formWhich might deprive your sovereignty of reasonAnd draw you into madness? Think of it.[The very place puts toys of desperation,Without more motive, into every brainThat looks so many fathoms to the seaAnd hears it roar beneath.] ”
