Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Never complain and never explain.
I can, therefore I am.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
After a storm comes a calm.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
