ADHD people are incredibly creative! They are those whose brain naturally refuses to conform to "what is not fun", in the words of the author. This feeling is right behind Artistry itself! Your mind is trying to say something very important.
I advise you to invest in finding what your flow is. For a moment think the way your brain works is a gift of the universe and things like Distraction, Hyperactivity and Never Ending Stream of Thoughts might in turn be confused with Graph Exploitation, Mind Stamina and Infinite Power of Association.
How can you take the most utility out of your "condition"? By using it as a tool for Creative Expression. We are all blessed to have so many options to do that. Fall in love with a project - something you care about so much you will likely be always motivated by it.
The System is totally broken. Many know that. Companies should see ADHD collaborators as a unique and rare kind of Problem Solvers and work hard to make sure their gift is well exploited. The full equation has got many parameters, but a good starting question is "how can we design an environment where my ADHD (or any other condition) can give their absolute best?".
Personally, I like to use my abilities thinking about The Future of Technology and expressing those thoughts through Software Development. If you vibe with that, message me. I would very much want to be your friend.
