Know or listen to those who know.

Expect problems and eat them for breakfast.

Begin to be now what you will be hereafter.

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

It's always too early to quit.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

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

To know oneself, one should assert oneself.
