The Relationship You Need to Get Right (Hewlettt and Marshall, p.131).
The authors studied one of the key relationships in creating successful leaders, the sponsor-protégé model. They discovered in the best of these relationships that the sponsor (or mentor) provides coaching, advocates for protégés, call in favors for them, and makes connections for them. On the other hand, protégés should be fiercely loyal, give 110% to any effort, and reciprocate. Further, both sponsor and protégé should subscribe to the “pay it forward” philosophy.
