Put off your imagination as you put off your overcoat when you enter the laboratory. Put it on again as you put on your overcoat when you leave.
My Dad hated his job. He sold overcoats but he wanted to make movies. He had a failed career working with the Ritz Brothers - they were like the Marx Brothers only a tier below. I always had a picture in my mind of him in a straw hat.
My overcoat is worn out my shirts also are worn out. And I ask to be allowed to have a lamp in the evening it is indeed wearisome sitting alone in the dark.
