Isolation is the one sure way to human happiness.

A sure way to lose happiness, I found, is to want it at the expense of everything else.

Gambling: The sure way of getting nothing for something.

The sure way to be cheated is to think one's self more cunning than others.

Progress requires setbacks; the only sure way to avoid failure is not to try.

To this light, then, would I recommend all, with mine own soul, - to this sure way of salvation.
