I have worked with some winners over the years. One guy in particular he had lost his drivers liscence and so I would pick him up on he way to the job site. One morning he is standing on the corner in his socks.
"yo man where's your boots"
"I uh left'um atta party last night we have to drive over there so I can geet'um"
On another job I sent him back to the truck to get something while I worked on something else. After I while he didn't come back so I went to see what he was doing. He was sleeping in the in the front of the truck laying across the front seat. After that I told the boss it was me or him.
And I have been know to take a nap on the job but I get my work done first, and don't do it where the client can see you.
That's just one of the winners I've had to work with over the years.
