The talent of success is nothing more than doing what you can do well, and doing well whatever you do without thought of fame. If it comes at all it will come because it is deserved, not because it is sought after.
Henry Wadsworth LongfellowTo be infatuated with the power of one's own intellect is an accident which seldom happens but to those who are remarkable for the want of intellectual power. Whenever Nature leaves a hole in a person's mind, she generally plasters it over with a thick coat of self-conceit.
Henry Wadsworth Longfellow
