The roughest road often leads to the top.
— Christina Aguilera

An inexhaustible good nature is one of the most precious gifts of heaven, spreading itself like oil over the troubled sea of thought, and keeping the mind smooth and equable in the roughest weather.
Washington Irving roughest quote

You know that fiction, prose rather, is possibly the roughest trade of all in writing. You do not have the reference, the old important reference. You have the sheet of blank paper, the pencil, and the obligation to invent truer than things can be true. You have to take what is not palpable and make it completely palpable and also have it seem normal and so that it can become a part of experience of the person who reads it.
— Ernest Hemingway

And when you see it the first time you put the film together, the roughest cut, is when you want to go home and open up your veins and get in a warm tub and just go away. And then it gradually, maybe, works its way back, somewhere toward that spot you were at before.
— Joel Coen

Time and the hour run through the roughest day.
— roughest quotation by William Shakespeare
