True.
Employees engaged in creative work are often more successful if they build "incubation" periods into the process. The incubation period is a phase of the creative process where an individual steps back from the problem they are trying to solve and allows their mind to work subconsciously on the problem. During this time, they may engage in activities that are unrelated to the problem, such as taking a walk or doing something else that allows their mind to relax and think freely.
