This document discusses how self-talk impacts success, particularly in sales. It observes that top sales performers generally have positive self-talk where they believe in their abilities and see opportunities, while poor performers have negative self-talk where they doubt themselves and focus on challenges. A key difference observed between a top salesperson and one who was dismissed was their mental messaging - the top performer conveyed messages of success to themselves and others, while the poor performer focused on negatives. The document suggests improving one's self-talk through positive affirmations and gratitude to impact outlook and results.
