“ One should as a rule 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, and is likely to interfere with happiness in all kinds of ways. ”
 Bertrand Russell, The Conquest of Happiness (1930). copy citation

“If on the other hand you find professional opinion discouraging, that is another matter, for professional opinion must always be treated with respect by beginners.
I think that in general, apart from expert opinion, there is too much respect paid to the opinions of others, both in great matters and in small ones. One should as a rule 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, and is likely to interfere with happiness in all kinds of ways. Take, for example, the matter of expenditure. Very many people spend money in ways quite different from those that their natural tastes would enjoin, merely because they feel that the respect of their neighbours depends upon their possession of a good car and their ability to give good dinners.” source
