As I know, Parkinson’s law is a method that can help us to focus and complete a task faster because we set the completion time. Rather than try to be lazy, we choose to complete the tasks as fast as possible. You get an Essay task on Monday from your teacher. You have to collect it on Friday. Then, after school, you take your pen and paper to write an essay for two hours. Finally, your task finishes before the due date. So, you have more time to relax until Friday.
