Ideas by themselves are roughly worthless. There's no market for them. There's no place where one can go and buy an idea.

Describing your idea in detail doesn't mean other people will copy it. First they'll have to be convinced it's a good idea.

If you ever tried to change anyone else's mind you know by now how hard that is.

Not even founders themselves can predict how well their own ideas will do.

Even if people are convinced your idea is a good idea, they'll still have to compare it to the existing idea they are already working on and see which one they're more likely to do well with.

An idea that is not dangerous is unworthy of being called an idea at all.

The value of an idea lies not in its novelty but in its capacity to reorganize perception.

Ideas are like fish - you must catch them when they swim by, or they're gone forever.

The most powerful ideas are those that seem obvious only in retrospect.

An idea is a feat of association, and the height of it is a good metaphor.

Ideas don't succeed because they are true, but because they are useful.

The gestation period for an idea is inversely proportional to its significance.

An idea is not truly yours until you've tested it against reality and it has survived.

The best ideas arrive unannounced and leave just as quietly if not welcomed.

Ideas are seeds that require the right soil of consciousness to grow.

The resistance an idea meets is often the measure of its potential value.

An idea becomes powerful not when it is thought, but when it is lived.

The marketplace of ideas is the only market where the best products often go unrecognized for generations.

Ideas are the architecture of reality - first we build them in our minds, then they build our world.
