I feel fantastic right now - in the last week, I have hyper focussed for several days to help a dear friend prepare for a court date (the kind of task that has "important/interesting to me" and "urgent" written all over it), and due to our preparation, it went really well for her. And I am happy, relieved and quite proud of us - while also feeling completely trashed from overtaxing my physical ressources in the process.
Absolutely worth it, though. I will, however, now take a break of several days.
