You want to finish your rule of prayer quickly, in order to give rest to your weary body? Pray fervently, and you will sleep the most peaceful, quiet, and healthy sleep. Do not hurry, then, nor say your prayers anyhow; by half-an-hour’s prayer you will gain three whole hours of the soundest sleep. Are you hurrying to get to the place of your service or your work? Get up earlier; do not sleep so long; and pray fervently—you will thus obtain tranquillity, energy, and success in your work for the whole day.
—St. John of Kronstadt, My Life in Christ
