> But not when you force to be bored by someone else. You are bored in a prison, you are bored during doing repetitive work, is it good for you too?

Arguably, yes. You learn to deal with discomfort, which is good for your mental health. Changing circumstances to avoid discomfort puts the power in externalities, whereas learning to deal with situations you don't like puts the power internally (you). The modern world trains us to run away from anything we don't like, and here we are.

Also, most people don't sit in a room voluntarily because they're looking to be bored (unless it's for meditation, but that's not the same thing). It's usually because of someone else.
