The vitality of thought is in adventure. Ideas won’t keep. Something must be done about them. When the idea is new, its custodians have fervor, live for it, and if need be, die for it.
An idea that is not dangerous is unworthy of being called an idea at all.
Ideas are like wandering sons. They show up when you least expect them.
Think for thyself one good idea, But known to be thine own; Is better than a thousand gleaned, From fields by others sown.
An apathetic or hostile attitude is the enemy of creative thought. Ideas, like people, flourish when they are welcomed and embraced.
All the good ideas I ever had came to me while I was milking a cow.
Every new idea is born drowning.
An idea is salvation by imagination.
The only people in the world who can change things are those who can sell ideas.
Every time a man puts a new idea across he finds ten men who thought of it before he did – but they only thought of it.
