 And I would watch how the guys that were doing the work that I was bringing the supplies for, what they were doing and how they were doing it. And I learned what not to do. That was the main thing. It wasn't so much how to do, it was what not to do. Because they would make a mistake and get towed off or they had to fix it. And I had to bring more materials to fix whatever they messed up. So I said, oh, I know not to do it that way. So I learned from the process of what not to do rather than what to do.
