Be thine own palace, or the world's thy jail.
Begin to be now what you will be hereafter.
What you do today can improve all your tomorrows.
It's always too early to quit.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
You never know what motivates you.
I can, therefore I am.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
I can only point out a curious fact. Year after year the Nobel Awards bring a moment of happiness not only to the recipients, not only to colleagues and friends of the recipients, but even to strangers.
