Selling is not a dirty word. Selling is the act of helping someone make a decision that serves them. The Brother who cannot sell is at the mercy of those who can.
The greatest salespeople listen 80% of the time and speak 20%. They diagnose before they prescribe. They walk away from poor fits.
Practice selling on small things. Negotiate at the farmer's market. Ask for the discount. Pitch thy ideas in meetings. Each rep builds the muscle.
The Seal of the Chamber
He who can sell can never be poor.
