Have more humility. Remember you don't know the limits of your own abilities. Successful or not, if you keep pushing beyond yourself, you will enrich your own life - and maybe even please a few strangers.
One of the illusions of life is that the present hour is not the critical decisive hour. Write it on your heart that every day is the best day of the year. He only is right who owns the day, and no one owns the day who allows it to be invaded by worry, fret and anxiety. Finish every day, and be done with it. You have done what you could.
Sir Walter, with his 61 years of life, although he never wrote a novel until he was over 40, had, fortunately for the world, a longer working career than most of his brethren.
Putting down on paper what you have to say is an important part of writing, but the words and ideas have to be shaped and cleaned, cleaned as severely as a dog cleans a bone, cleaned until there's not a shred of anything superfluous.
So in writing, there is always a right word, and every other than that is wrong. There is no beauty in words except in their collocation. The effect of a fanciful word misplaced, is like that of a horn of exquisite polish growing on a human head.
There should be a law that no ordinary newspaper should be allowed to write about art. The harm they do by their foolish and random writing it would be impossible to overestimate--not to the artist but to the public.... Without them we would judge a man simply by his work; but at present the newspapers are trying hard to induce the public to judge a sculptor, for instance, never by his statues but by the way he treats his wife; a painter by the amount of his income and a poet by the colour of his necktie.
Though there is one part of writing that is solid and you do it no harm by talking about it, the other is fragile, and if you talk about it, the structure cracks and you have nothing.
Except I'm aware that as a writer you can't get away with as much writing for children as you can with adults. Children have much more finely tuned senses of justice, morals, and ethics. They are much more Platonic: children are symmetrical, before we begin to fragment them with our own nonsensical ideas and squelch their natural joy in knowledge.
Great geniuses have the shortest biographies. Their cousins can tell you nothing about them. They lived in their writings, and sotheir house and street life was trivial and commonplace. If you would know their tastes and complexions, the most admiring of their readers most resembles them.
