To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

Expect problems and eat them for breakfast.

Be gentle to all and stern with yourself.

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

Go for it now. The future is promised to no one.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

Without hard work, nothing grows but weeds.
