It is impossible that happiness, and yearning for what is not present, should ever be united.

It is impossible for a man to learn what he thinks he already knows.

Happiness and freedom begin with a clear understanding of one principle: Some things are within our control, and some things are not.

It is not my place in society that makes me well off, but my judgements, and these I can carry with me... These alone are my own and cannot be taken away.

Even as the Sun doth not wait for prayers and incantations to rise, but shines forth and is welcomed by all: so thou also wait not for clapping of hands and shouts and praise to do thy duty; nay, do good of thine own accord, and thou wilt be loved like the Sun.

Never say of anything I have lost it, only say that I have given it back.

What concerns me is not the way things are, but rather the way people think things are.
