I do score quite high (total 44, inattentive scale 19, hyperactivity/impulsivity scale 25), yet I'm not convinced: at work I almost always manage to get things done well and in time, and I'm generally considered accomplished by my peers and managers, though maybe strange and over the top.
People with ADHD can most definitely be productive and generally considered accomplished. They just tend to have put a lot of effort in, their whole lives, in order to get there, and may have developed a lot of cool techniques to get there. Treatment itself is about improving these techniques (and finding helpful medications, the two parts work together.)
The stimulant caffeine is a popular alternative (provided you’re not overly sensitive to it [it can cause heart palpitations and anxiety], and don’t take it too late in the day) — lots of people use it to self-medicate ;)
Not to harp on about medications, but there are “non-stimulant” medications used to successfully treat ADHD as well, such as Strattera.
On the non-medicine side, techniques like bullet journaling are useful, also having “accountability partners” — friends or groups you report in with each week to check on each other’s progress; things like that.
