“Nothing is more conducive to peace of mind than not having any opinions at all”

“The superiority of one man's opinion over another's is never so great as when the opinion is about a woman.”

“Do not mind anything that anyone tells you about anyone else. Judge everyone and everything for yourself.”

“Whether you think you can or think you can't, either way you are right”

“New opinions are always suspected, and usually opposed, without any other reason but because they are not already common”

“It often takes more courage to change one's opinion than to stick to it”
