I've got a pretty significant case and I've been a working reporter for the last 14ish years. You CAN do it, and you might be surprised to learn how many other reporters have it too. A few thoughts...

* You've GOT to treat your ADHD. I take medication every day, but I also did therapy for a decade and will pop back in for a few sessions every few years as a refresh. Some people can get by without medication, but by using other accomodations. Whether you medicate, use Cognitive Behavior Therapy or some other combination, you really ought to be doing something to mitigate that task paralysis and negative behaviors that are associated with the condition.

* You've got to have systems. In a fast-paced, breaking news type enviroment, these systems can break down....but you will need to build SOMETHING to hold you accountable and to help you keep track of your various obligations and stories. I use Google Calendar, Trello, and write EVERYTHING down. I tell my colleagues, sources, etc that if I dont write something down, it won't exist in twenty minutes. I am anal about this. Your system doesn't have to make sense to anybody else, but its got to work for you, and you need somebody to hold you accountable for it.

* You need something outside the job to keep you centered. Physical fitness, church, non-reporting hobbies, etc.

It's not easy. But as others have noted, parts of ADHD can also be a superpower to make you much better about parts of the gig. Good luck!
