Even if all the experts agree, they may well be mistaken.

One should respect public opinion in so far as is necessary to avoid starvation and to keep out of prison, but anything that goes beyond this is voluntary submission to an unnecessary tyranny

Your life is enough, don’t be concerned with others. And I tell you that if you can live unconcerned your life will flower, and then others can share in it. You would like to share, and you can give much to others, but first you must stop thinking about others and what they are thinking about you.

When you’re anonymous, other opinions shrink next to the sounds in your own head.

It is not the opinion of the common man that matters, but the opinion of men for whom you admire and truly respect.
