Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
It's always too early to quit.
The wise does at once what the fool does at last.
Only the educated are free.
Always desire to learn something useful.
Quality is not an act, it is a habit.
After a storm comes a calm.
If you've got a talent, protect it.
The artist is not responsible to any one. His social role is asocial... his only responsibility consists in an attitude to the work he does.
