“It is a pity that, as one gradually gains experience, one loses one's youth.”

“The victory one would gain after a whole life of work and effort is better than one that is gained sooner.”

“Quick work doesn't mean less serious work, it depends on one's self-confidence and experience. In the same way Jules Guérard, the lion hunter, says in his book that in the beginning young lions have a lot of trouble killing a horse or an ox, but that the old lions kill with a single blow of the paw or a well-placed bite, and that they are amazingly sure at the job... I must warn you that everyone will think that I work too fast. Don't you believe a word of it. Is it not emotion, the sincerity of one's feeling for nature, that draws us, and if the emotions are sometimes so strong that one works without knowing one works, when sometimes the strokes come with a continuity and coherence like words in a speech or a letter, then one must remember that it has not always been so, and that in time to come there will again be hard days, empty of inspiration. So one must strike while the iron is hot, and put the forged bars on one side.”

“It is not only by one's impulses that one achieves greatness, but also by patiently filing away the steel wall that separates what one feels from what one is capable of doing.”

“To do good work one must eat well, be well housed, have one's fling from time to time, smoke one's pipe, and drink one's coffee in peace”

“One must work and dare if one really wants to live.”

“How rich art is, if one can only remember what one has seen, one is never empty of thoughts or truly lonely, never alone.”
