One thing that always infuriates me is seeing a top salesperson attempt to change industries only to be turned down because he doesn't have experience in that particular field. In fact one of my best friends right now, who happens to be one of the best salesmen I've ever met, is trying to switch careers but every manager says, "I can't hire you because you don't have experience in our particular industry."
This is idiotic because selling is selling. If you can sell one thing you can sell another. It's the same process and anyone with half a brain can pick up the product knowledge very quickly. This came to mind today because I've noticed a lot of Army recruiters have been buying my book lately, and today's news says that the National Guard is adding 1,400 recruiters because the war in Iraq has made recruiting for the Guard much more difficult.
The fact that such diversified salespeople as Army recruiters and insurance agents are both getting great results by using my prospecting system is the most solid proof I can think of that all selling is the same. If you're a manager, don't ever turn down a salesperson with a solid track record just because he or she hasn't worked in your industry. If you do you're turning down a potential top producer.
