To those unacquainted with sailing, a vessel beating to windward always looks erratic.
— Joseph Furnas, biographer of Robert Louis Stevenson
Life, as you may have noticed, is a voyage to windward. Everything good in it lies at the exact point of the compass from which the wind is blowing, which means you have to tack, zigzag back and forth close-hauled into the wind, gaining only a little forward progress on each tack.
What seems to be an erratic course is in fact the fastest, the only, route to your destination.
