"Never argue with a fool, onlookers may not be able to tell the difference" — Mark Twain

I have spread my dreams beneath your feet; Tread softly because you tread on my dreams

Do you think yourself wise? Then there's a donkey inside your waistcoat

An illusion of depth often occurs if a blockhead is a muddlehead at the same time

Look before you leap.

The more perfect a thing is, the more susceptible to good and bad treatment it is

The chief danger in life is that you may take too many precautions

Mark Twain Quote
