Sorry I can’t be of any help, but I relate FULLY!! I can’t make a routine for anytbing because my brain HATES routine!! It’s immediately too boring by the 3rd or 4th day. I would rather live spontaneously and can find some success with that. It at least can provide some motivation sometimes because I’m more attentive and devoted to something “new, spontaneous.” But know you’re not alone. I see so much written about how ADHD thrives with routine and structure, but NOT mine!
