If I asked you to stand in front of a tree, gave you some pencil and paper and asked you to produce the best possible drawing of that tree, how long would it take you?
While performing studies, artists do this differently. They maybe also be asked to draw the best possible tree, but with the constraint of doing it in 2 minutes. And then, they are asked to do this over and over again.
What is the best possible blogpost you can write in half an hour?
What is the best possible song we can compose in two hours?
What is the best possible scene we can shoot in 5 takes?
What is the best possible dish I can make with these five ingredients within an hour?
Shooting for perfection can be meaningless without meaningful constraints.
