The only thing constant in life is change

The sure mark of one born with noble qualities is being born without envy.

We often boast that we are never bored; but yet we are so conceited that we do not perceive how often we bore others.

We rarely ever perceive others as being sensible, except for those who agree with us.

What is called generosity is usually only the vanity of giving; we enjoy the vanity more than the thing given.

Few things are impossible in themselves: application to make them succeed fails us more often than the means.
