"We are so vain that we even care for the opinion of those we don't care for" — Marie von Ebner-Eschenbach

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

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

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

To do just the opposite is also a form of imitation

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