Bob Thornton builds houses. His father was a builder and Bob learned the job from his father. In fact, they run a construction company together. Bob's company is big.
Big enough for Bob to stop building and manage the company. But Bob builds because he loves the work. He puts the personal touch on everything he builds. That is part of the reason they are so successful.
On weekends, Bob's son comes with him to the construction site and builds too. It's a family of builders.
