Hard disagree with ‘great to be bored’ - being bored is one of the worst possible feelings, that you’re wasting your time doing nothing when there is almost certainly something you would rather be doing.

As a child I used to hate the feeling of boredom, knowing that I could be doing something I wanted to do. As an adult I am hardly ever bored, and it’s a strict improvement, never have I ever found myself wishing I could just go back to being bored.

Boredom is such a negative emotion that learning to manage it effectively becomes an essential life skill. Learning to set yourself up for success / be prepared required forethought to anticipate the possibility of boredom and come prepared to deal with it. Acting out on boredom is childish, learning to keep yourself occupied so you don’t become bored is mature.
