Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
If you've got a talent, protect it.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
It's always too early to quit.
What you do today can improve all your tomorrows.
Never complain and never explain.
If you're going through hell, keep going.
Always desire to learn something useful.
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.
