There is no more miserable human being than one in whom nothing is habitual but indecision.

A man is never more truthful than when he acknowledges himself a liar

Let the fictitious sources of pleasure be as near as possible to the true.

... when you have eliminated the impossible, whatever remains, however improbable, must be the truth

It is not well to make great changes in old age

Habits wear more constantly and with greatest force than reason, which, when we have most need of it, is seldom fairly consulted, and more rarely obeyed
