To me, obsessing means that I have this enormous internal drive to do something I care about. The result is that I'm laser-focused on achieving my goal. If I were to make a list of "things I've done that I'm proud of", I'm certain 80% of them were obsession-driven. My Ethereum thingy was made by spending an entire long weekend on it, writing and drawing from dawn till dusk. When I wrote my article a few months ago, I spent most of my evenings and weekends on that thing. I "wasted" an entire Sunday on creating a timelapse because I became obsessed for a bit with open-source Sentinel satellite imagery.
Just don't feel bad for pressing the pause button on your obsession and you should be fine. :)
