It's a good thing that ADHD has nothing to do with "not being able to focus easily" then.

ADHD means "I don't choose what I focus on", which poses some management challenges, but in an environment where there's always a lot of various interesting tasks to choose from and a team of people where others can take care of things you end up neglecting because your focus has changed, one can still thrive sitting behind a desk. In fact, my ADHD barely ever takes me away from my desk (unless making it too cluttered to sit there and moving with a laptop to a couch counts).

Maintaining your health, house and relationships is not as easy though.
