This is so absolutist. You must have a boring life. Sometimes it's about making things fun, sometimes it's about making fun things, and sometimes it's about both.

Driving a car is fun. Building a custom hotrod isn't.

Going to the museum is fun. Learning to paint isn't.

Playing a video game is fun. Writing a video game isn't.

Going to a concert is fun. Playing a gig isn't.

Eating is fun. Gardening isn't.

Oh, wait, none of that is universally true.
