I can, therefore I am.
Only the educated are free.
Always desire to learn something useful.
Who seeks shall find.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
It's always too early to quit.
If you can dream it, you can do it.
Never complain and never explain.
Quality is not an act, it is a habit.
It always makes me sad when I think of how I saw Wagner wasting his vitality, not only by singing their parts to some of his artists, but acting out the smallest details, and of how few they were who were responsive to his wishes.
