Reading poetry is like undressing before a bath. You don't undress out of fear that your clothes will become wet. You undress because you want the water to touch you. You want to completely immerse yourself in the feeling of the water and to emerge anew.
Usually, when people get an idea, they are eager to start acting immediately, immerse themselves in the process without creating a system of actions, without being knowledgeable of the matter, without analyzing and estimating everything beforehand
Actors like Daniel Day-Lewis, Gary Oldman, they totally immerse themselves in their parts.
