I'm an ADHD OG myself, and take adderall to this day, but my experience is a bit different. Without adderall (and usually coffee) I can organize, email, hustle and promote like nobody's business... but I cannot program, finish anything or do much but bounce between 2-5 minute tasks in 30 second intervals. You can't implement metaclustering or write a cohesive paper in 30 second intervals. It's not that I'm not creative on tasks requiring more focus, it's that they are not even accessible to me without the drug, and that these 30 second bouts of activity feel like they are rewarding even if they don't amount to anything. With adderall I'm creative on a longer attention window, and can work for rewards without very fast payoff.
