Bro, not everybody is a morning person. I appreciate you sharing what works for you, but for one if OP does in fact have ADHD, that comes with insomnia sometimes so it is unlikely they’ll be getting up early, and if they do, they won’t want to do jumping jacks or take a morning shower regardless of the temp. Also, breakfast is hit or miss too because people with ADHD also have symptoms of depression and anxiety so they’re stomachs won’t be prepared for that probably.
