Which can be correct course of action. If I stuck trying to figure out how to solve some hard problem it is very good ide to switch for a while and magically the solution comes back later on since brain still manages to do something in background. Alternatively if I have to do whole lot of monotonous non rewarding work for whatever reason I would go nuts if I try to finish it in one step (considering it is long enough)
