Be yourself not your idea of what you think somebody else’s idea of yourself should be.
Be less curious about people and more curious about ideas.
An idea that is not dangerous is unworthy of being called an idea at all.
An idea ran back and forward in his head like a blind man knocking over the solid furniture.
An idea is a thought. It’s a thought that holds more than you think it does when you receive it. But in that first moment there is a spark.
An ‘idea’ is prepared only on the soil of very hard work, but certainly this is not always the case.[Nur auf dem Boden ganz harter Arbeit bereitet sich normalerweise der Einfall vor. Gewiß: nicht immer.]
All great ideas are dangerous.
A new idea comes suddenly and in a rather intuitive way. But intuition is nothing but the outcome of earlier intellectual experience.
