Problems are not stop signs, they are guidelines.

To know oneself, one should assert oneself.

Know or listen to those who know.

Only the educated are free.

Without hard work, nothing grows but weeds.

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

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

If you've got a talent, protect it.

By failing to prepare, you are preparing to fail.
