When a person runs dry inside, they look outside for what they lack. But the deeper mind has a hidden source that keeps working through the empty stretches, renewing what daily life uses up. The old writers called this source God, sensing rightly that it runs deeper than the everyday self.
A man in midlife who had everything he wanted still felt dead inside, and no success could touch it. What healed him was turning inward and letting that deeper center guide him. He stopped running dry because the spring within kept feeding him, and that spring does not depend on luck, so it never fails.
