Work can be broken down into two different activities. The first is deciding what to do and the second is doing it.
The former requires creativity while the latter requires putting in the time to perform an activity with relatively less brain power.
Since the latter requires less brain power, it’s possible to spend extended periods of time, which I define as more than 12 hours a day, doing it.
Creativity, on the other hand, comes in short bursts. You can’t be creative for 12 hours a day. My creative periods last for 4 to 5 hours a day at best.
As a result, creative roles spend less time working than roles focused on carrying out a predefined task. However, this does not mean that creative roles produce less output as correct decision making is a higher leverage activity than task execution.
In roles that require both creativity and performing predefined tasks, it’s useful to set your daily schedule to allow enough time for your high value creative bursts to occur in the environments and the times of the day when they’re most likely to surface, while spending the remaining time on performing predefined tasks.
