"Constant, quiet, calm practice means regular periodical practice continued for sufficient time to be effective. The results of this practice are cumulative. Little appears at the beginning, but much later on. The time given at any one sitting need not be great, for the quality of the work is more important than the quantity. Little and frequently is better than much and rarely. The sittings may be once or twice a day, or even three times if they are short. Once, done well, will bring about rapid progress; three times, done indifferently, will not. Sometimes the people who have the most time to spare succeed the least, because they feel that they have plenty of time and therefore they are not compelled to do their very best immediately; but the man who has only a short; time available for his practice feels the need of doing it to perfection."
