This is why I like sports, or more specifically "walled" games.

The "walls" are the rules and the task is to figure out how to succeed within those rules. Succeed is up to perspective in many instances.

This encourages creativity. It's why I love baseball, cuz the rules are constantly evolving as people game them. It's so joyful seeing people exploit the rules they agreed to play by.

Limits force us to think INSIDE the box. It's a lot of fun.

Communal boredom is also very important. Being bored with friends is an amazing launching pad for new ideas and thinking.
