Problems are not stop signs, they are guidelines.

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

Only the educated are free.

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

Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

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