Be specific and quantify. For example, "I want to close 20 new 1-year annual contracts," or "I want to sell thirty new 90-Day Investment Programs," or "I want to add fifty new patients to my practice."
Include industry, job title, age bracket, how they make buying decisions, where are they and how you find them, and anything else about your ideal customer that will be helpful.
Select your most popular product/service. Such as, "One 90-Day Investment Program grosses me $20,000." Feel free to ball-park the amount, and if it is ongoing customer engagements, how much do you gross in a year from their doing business with you.
