An expert is a person who avoids small error as he sweeps on to the grand fallacy.
Where facts are few, experts are many.
—Donald R. Gannon
My definition of an expert in any field is a person who knows enough about what's really going on to be scared.
—P. J. Plauger
Always listen to experts. They'll tell you what can't be done and why. Then do it.
—Robert A. Heinlein
In the beginner's mind there are many possibilities. In the expert's mind there are few.
Don't put your faith in anyone. You have it all inside you. You're always asking the masters. Why don't you ask yourselves? Forget the masters.
