Problems are not stop signs, they are guidelines.

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

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Always desire to learn something useful.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

It's always too early to quit.

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