Be gentle to all and stern with yourself.

Wherever you are - be all there.

It's always too early to quit.

Problems are not stop signs, they are guidelines.

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

Do not weep do not wax indignant. Understand.

What you do today can improve all your tomorrows.

Always desire to learn something useful.

To know oneself, one should assert oneself.
