He learned the trade by working it.
He grew up in the Zürcher Oberland. He learned the trade the way the trade is still best learned. From the floor, slowly, with his hands.
He completed a three-year apprenticeship as automotive technician in Switzerland, then spent several years on the floor of a tire shop. He was promoted to foreman, then to selling tires across a counter. On weekends he ran a small private trade in used tires for friends and neighbours.
In his mid-twenties he moved into car sales. A few weeks into the first role, at a Swiss Opel and Chevrolet house founded almost a hundred years earlier, the owner walked across the floor to tell him plainly that he was looking at the best sales start the firm had seen in its history. He moved through two more dealerships and finished as sales manager at a Toyota Lexus house in the canton of Zürich.
The lesson of those years was simple. The trade is learned by working it. Anything else is decoration.
