Men, young men especially, would do well to consider whether in their careers they are seeking excellence or greatness. Excellence is godly (ref Col 3:23) and it is within a man's control. Whatever you do, do it heartily as unto the Lord.
Seeking greatness, on the other hand, is usually an ambitious quest for significance, reputation and importance. Besides being things not fully in a man's control, they also involve self-exaltation. And if a man fully gives into these desires he may find his life in ruins.
Men, we must heed the wisdom of Solomon here (the Proverbs and the Preacher) lest we learn the hard way.
