Know or listen to those who know.

Without hard work, nothing grows but weeds.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

I can, therefore I am.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

Never complain and never explain.

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