This book really sounds like one I'd enjoy @neeqi. I can't see it on Audible which is a shame as I tend to listen to many more than I can read. It is always nice to have some paper books though so I will look for this one.
I try to be mindful instead of bored and then the word 'bored' doesn't really even exist. I remember going camping once with a former friend. We set up the tents, lit the fire and sat down. Less than about a minute later he said, "OK, so what do we do now? I'm bored". I replied, "You can do what you like, I'm happy to just sit". He got quit angry at me, which is ok and doesn't bother me, but I wish he'd understood why it's ok to just sit.
This might sound weird and might be off tangent a bit but I enjoy sitting in shopping centres. Not to buy anything but to just experience. Bustling activity all around me, kids running around, people constantly talking, on their phones, hunting for items, forever looking for distractions, while I just sit and absorb it all. It's like being a calm center in the middle of a chaotic storm. I find it very peaceful for some reason as long as I'm observing my internal reality and not reacting to external reality.
