Routine tasks are, as others have commented, essential to pay the bills. And they come with a deadline, because someone out there is expecting the task to be done--whether it's the bills you need to pay, or a report you need to prepare for your boss. So logically, if the key difference between a routine task and a creative task is the lack of deadline and structure, wouldn't it make sense to have people involved for your creative projects too? So collaborative creative projects are likely to get done, while solo creative projects will probably run slower.
