Direction from someone who sees further is worth more than the harvest it produces.
Energy follows the line the eyes are held on, which is why attention spread across ten fields returns less than attention kept on one. The narrowing concentrates effort, concentrated effort produces a harvest that the same hours would not otherwise yield, and a harvest is what buys a person a future instead of another day.
Being told where to look, and where the water is, amounts to inheriting another person's experience without paying its tuition. A woman newly arrived in a country had no way to see which field was safe; that distinction existed only from where he stood, and everything she gathered afterward came along the line he set for her eyes. Refusing direction like that out of pride costs exactly the years it would have let a person skip.
