Light bulb moments

In work and personal life, ideas have been created and thrown around at an increasing pace lately.  Some big, some small.  Some have already burned out while others have promise.  While looking for quotations about ideas though, it became clear that many people talk about the idea of something and not an idea as a thing itself.  Below I have put together a few quotes that discuss idea itself.

“An idea that is not dangerous is unworthy of being called an idea at all.” - Oscar Wilde

“Everyone is in love with his own ideas." - Carl Gustav Jung

“If you want to kill any idea in the world, get a committee working on it.” - Charles F. Kettering

“Nearly every man who develops an idea works it up to the point where it looks impossible, and then he gets discouraged. That's not the place to become discouraged.” - Thomas Alva Edison

“If you have one good idea, people will lend you twenty.” - Marie Von Ebner-Eschenbach

“An idea must not be condemned for being a little shy and incoherent; all new ideas are shy when introduced first among our old ones.” - Samuel Butler
