Good ideas are a dime a dozen, bad ones are free.

Life is good when we think it's good. Life is bad when we don't think.

I don't think that the Left has a monopoly on bad ideas. I don't think the Right has a monopoly on good ideas.

The way to get good ideas is to get lots of ideas and throw the bad ones away.

The good ideas will survive.

You see a lot of good ideas or well-written scripts that are bad ideas.
