Adam Grant says that leveraged well, procrastination can have powerful benefits like enhanced creativity and huge leaps in critical thinking.  This approach is especially good for unsolved tasks.

However, how should I explain this to my kids so that they don't feel they can continue allowing their rooms to look like bottoms of bird cages in the name of creativity?  How to ensure they don't start to believe forgetting or putting off projects and assignments is their ticket to intellectual brilliance?

The problem is that this isn't the kind of procrastination that's beneficial.  Procrastination only helps divergent thinking and incubation as long as you don't wait too long which, ironically, often happens when you are disorganized.

Goldilocks procrastination. That is the goal.
