Reminds me of my doctor who thought that adhd was not real and his solution to my issues was "just do it lmao"
Also, saying “regardless of diagnosis” is invalidating the real need for accommodations. People with ADHD often require not just personal effort, but systemic support, whether that’s in school, work, or healthcare.
Usually such techniques tend to not work when they are suggested by people who haven't experienced the consdition and haven't put serious thought into them.
