The single thing that helps you make sale.
A lot of people find it hard to convert and make sales. Making sales is not limited to people selling online only, it is also in everyone's day to day activities. If you are as politician and you just won an election, you just successfully sold yourself to the people and they rewarded you by giving you their mandate. If you just successfully get married to a girl, you have sold yourself to her and by doing so, you've made her believe in you to want to spend the rest of her life with you. Everyone is a sales person. We just don't always know we have the skill. Now, ask yourself what you did different to connect with that your new friend, your new lover, your new job. What would you say is your best weapon to selling?
