Expect problems and eat them for breakfast.

Know or listen to those who know.

Be thine own palace, or the world's thy jail.

To know oneself, one should assert oneself.

It's always too early to quit.

The most effective way to do it, is to do it.

Be gentle to all and stern with yourself.

The wise does at once what the fool does at last.

Without hard work, nothing grows but weeds.
