I have two friends. They are very different. One of them is a co-founder and CEO of one of the largest private companies in their industry. Another one is a physiotherapist.
Both are successful. And they have one thing in common.
The first one founded his manufacturing company with his roommate almost 30 years ago. Now they own more than 40 factories in 9 countries. They produce insulating materials for construction. When they began, they had two product groups in their lineup. Now, 30 years later, they have six. And he believes it is more than enough.
They are market leaders because of their exceptional efficiency. They can offer their customers both perfect quality and low prices. And he believes that if he decided to widen their product range, it would have been difficult for them to keep such a high level of efficiency.
The physiotherapist is not a millionaire. He works in a local hospital, but he is so popular that people must wait weeks to see him…
