 All intelligent thoughts have already been thought; what is necessary is only to try to think them again. |
| What is not started today is never finished tomorrow. |
| All theory, dear friend, is gray, but the golden tree of life springs ever green. |
| The hardest thing to see is what is in front of your eyes. |
| We are never deceived; we deceive ourselves. |
| The most happy man is he who knows how to bring into relation the end and beginning of his life. |
| To the person with a firm purpose all men and things are servants. |
| Be above it! Make the world serve your purpose, but do not serve it. |
| The unnatural, that too is natural. |
| Everything in the world may be endured except continual prosperity. |
| We know accurately only when we know little, with knowledge doubt increases. |
| Upon the creatures we have made, we are, ourselves, at last, dependent. |
| The biggest problem with every art is by the use of appearance to create a loftier reality. |
| Know thyself? If I knew myself I would run away. |
| Whoever wishes to keep a secret must hide the fact that he possesses one. |
| A clever man commits no minor blunders. |
| I can tell you, honest friend, what to believe: believe life; it teaches better that book or orator. |
| Common sense is the genius of humanity. |
| Music is either sacred or secular. The sacred agrees with its dignity, and here has its greatest effect on life, an effect that remains the same through all ages and epochs. Secular music should be cheerful throughout. |
| It is in self-limitation that a master first shows himself. |
