Banal: Overeating/overdrinking/overconsuming, sitting around, reading reddit/HN for hours, playing video games or twitch.
Not banal: Challenging yourself to new activities or hobbies that require skill. Seeing the world, interacting with other people IRL. Learning (new topics, reading, etc). Building things. Getting out of your comfort zone.
Essentially, being passive/not learning/not engaging vs. learning/challenging oneself and trying to be more than you are.
