Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Only the educated are free.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind put into nature.
