Description Obsessed
No matter what it is about - for your brain, there are basically only two options: complete disinterest, which is expressed in an attention span with a half-life of a few seconds, or a state of boundless enthusiasm. And unfortunately, you are also pretty powerless when it comes to your brain's decision about what deserves your attention and what doesn't.
You can try to balance the switch in the middle, but that usually doesn't work particularly well. At least not in the long run. Therefore, you should take advantage of it when a topic doesn't let you go and you are on your way to becoming the new expert in the field. You never know when the switch might suddenly flip again.
