Metaphor

Difference between cleverness and foolishness is exactly 5 minutes. We all as humans are similar to each other and to say that one is superior to other based on his cognitive skills is foolishness in its purest form. 

The metaphor is collateral to a famous metaphor “All ingenious is simple, and all simple is brilliant, A little man likes to hide his insignificance behind complex things” - by Joseph Goebbels. All the complex things ever said, ever invented, ever happened now from a span of time look brilliantly easy. However, try to prove the “BIg Bang” theory without ideas to start, invent a lightbulb or convince 200 million unlettered civilians to unite under your control.  

Explanation: Cleverness is just 5 minutes away from stupidity. Moreover, compound interest compound those 5 minutes into a whole eternity.
