Have you ever come across this article in the Economist, summarizing research providing evidence that ADHD is a legacy of our nomadic past when ADHD traits conferred an evolutionary advantage?
My takeaway is that entrepreneurship is one of the few areas of modern life where ADHD might actually be a help rather than a hindrance.
It could be a good thing in the right environment like a startup.
Trying to organize then execute something could take a month of back and forth and planning. If you skip that step, you can get it done in a week then plan afterwards.
The only way I have found it working is to outsource my scheduling to someone else. I believe that explains why many people are diagnosed during college. College is much less restrictive than school and as a consequence people have to do their own planning.
