A man worked for the engineering department at an oil company. His job as an adviser was to guide the rookies into professionalism. Once his mentees had learned all they could from him they would step out and assume a loftier position elsewhere with a larger salary. The company would lose one engineer every year, but would foresee this coming and hire another so productivity was never effected. This went on for many years until the adviser had aged well enough, and his own advice was being reciprocated around the country by his previous mentees, now advisers themselves. On his last day he stared at his empty desk and chair before walking away. His boss, and friend spoke with a sense of content and rest. “Don’t worry; we’ll find a way to fill it.”
The adviser patted his friend on the back. “We lose one every year, but I never thought it would be me.”
