Thoreau writes in his journal:
Nothing goes by luck in composition. It allows of no tricks.The best you can write will be the best you are. Every sentence is the result of a long probation. The author’s character is read from title-page to end. Of this he never corrects the proofs. We read it as the essential character of a handwriting without regard to the flourishes. And so of the rest of our actions; it runs as straight as a ruled line through them all, no matter how many curvets about it. Our whole life is taxed for the least thing well done; it is its net result. How we eat, drink, sleep, and use our desultory hours, now in these indifferent days, with no eye to observe and no occasion [to] excite us, determines our authority and capacity for the time to come.
