Hi Richard,
This reminds me of partaking in nanowrimo ( national novel writing month ), back in November 2019.
Although a month of forced writing ( and having to average over 1600 words a day to make my goal ) made me sick and led to 50k words of 'novel material' that I never managed to turn into a novel, I also learnt a lot from this experience. What is even cooler is that it led to what is now my future ( little ) books series based around the character of 'Hypersensitivosaurus'.
Congratulations on your streak and don't feel bad about taking a break from creativity every now and then. You deserved it. Also, health and sleep are underrated.
