Problems are not stop signs, they are guidelines.

It's always too early to quit.

To know oneself, one should assert oneself.

Expect problems and eat them for breakfast.

Without hard work, nothing grows but weeds.

Quality is not an act, it is a habit.

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

Things do not happen. Things are made to happen.

Know or listen to those who know.
