Only the educated are free.
Always desire to learn something useful.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
I can, therefore I am.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
If a weakly mortal is to do anything in the world besides eat the bread thereof, there must be a determined subordination of the whole nature to the one aim no trifling with time, which is passing, with strength which is only too limited.
