At the core, good selling is a very, very simple process.
1. Learn your prospect's pain and how bad it is.
2. Figure out if what you sell will relieve some, or all of their pain.
3. Find out how much getting rid of their pain is worth to them.
If your known to be a decent, trustworthy person, steps 1-3 go smoothly, and what you have to sell meets what they want to spend to relieve their pain, you'll usually end up with a sale.
Sounds so simple, right?
But is it?
