I don't consider myself to have ADD, but I have taken Adderall. It increased my ability to focus, focusing on tasks is rewarded in society, and I felt like the positive effects of it made me a better version of myself. I stopped because I didn't appreciate some of the negative side-effects.
It seems common for people who take stimulants to feel like they're a better version of themselves while experiencing the positive side-effects of the medication irrespective of an ADD diagnosis. If you agree, I wonder how you came to the conclusion you were at a competitive disadvantage compared to the norm rather than simply having a leg-up against the norm once medicated.
And sorry if probing is disrespectful. No ill intent here. Just idle curiosity.
