Problems are not stop signs, they are guidelines.

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

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

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

Only the educated are free.

To know oneself, one should assert oneself.

If you've got a talent, protect it.
