In a widely reported interview across the papers, football über-Manager Alex Ferguson talked about many things Man U and him. During this, he crossed into territory with resonance for us sellers.
When talking about how to deal with people that all of a sudden have the world beating a path to their door, he felt a duty to first help keep their feet on the ground. The direct quote I liked applies to anyone either running a sales team where there are high achievers and the recently promoted, or indeed any salesrep that themselves is bountifully rewarded and now enjoys a newly enhanced role.
“I hammer it into them that the work ethic is what got them through the door here in the first place and they must never lose it.”
