Why paint with a time limit?

Generally there is no need to give yourself a time limit unless you are having trouble keeping your painting loose. Overworked paintings can easily become boring and lose their spontaneous look. So unless your goal is a realistic painting, the time limit allows you to practice to not focus on details and instead focus on large shapes and value difference of the subject.
