50 years of sales: What I didn’t learn in school
After five decades in the field, I’ve realized that the most vital sales lessons aren't found in textbooks. Success is built on human psychology and the resilience of the mind.
Sales is not a technique. It is the quality of your thinking. Most sales professionals search for better scripts, better tools, or better closing lines. Few stop to examine the deeper layer: how they actually think about customers, value, responsibility and their own role. This pillar explores the foundation of sustainable sales success — mindset, clarity, psychological maturity and decision-making discipline. After 50 years in sales, one lesson stands above the rest: Unclear thinking always leads to poor decisions. Technology evolves. Markets change. But the quality of thinking remains the ultimate differentiator.
