Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
Begin to be now what you will be hereafter.
I can, therefore I am.
Science is a differential equation. Religion is a boundary condition.
