A mediocre idea that generates enthusiasm will go further than a great idea that inspires no one.
Daring ideas are like chessmen moved forward; they may be beaten, but they may start a winning game.
Ideas are like rabbits. You get a couple and learn how to handle them, and pretty soon you have a dozen.
The mind, once stretched by a new idea, never returns to its original dimensions.
The best way to have a good idea is to have a lot of ideas.
To have a great idea, have a lot of them.
A man may die, nations may rise and fall, but an idea lives on.
The best revenge is the massive success.
A great idea is usually original to more than one discoverer. Great ideas come when the world needs them. Great ideas surround the world's ignorance and press for admission.
Whatever you can do, or dream you can, begin it. Boldness has genius, power and magic in it.
Great minds discuss ideas; average minds discuss events; small minds discuss people.
If you can dream it, you can achieve it.
If you can dream it, you can do it.
Your time is limited, so don't waste it living someone else's life.
The difficulty lies, not in the new ideas, but in escaping from the old ones.
All great ideas are dangerous.
If you can dream it, you can make it so.
There's no good idea that cannot be improved on.
Get a good idea and stay with it. Dog it, and work at it until it's done right.
You can have brilliant ideas, but if you can't get them across, your ideas won't get you anywhere.
