Referrals are every salesperson's greatest ally. Simply put, a referral is
the most powerful lead you will ever work with. You will obtain more
clients, with less effort, through referrals than through any other
marketing tool. In fact, the value of a qualified referral is so great
that one seasoned sales veteran has commented as follows: "A qualified
referral is more valuable than a thousand gold-leaf brochures."
