What is a good career for someone with ADHD inattentive?

Yes. Follow your calling, adhd is a diagnosis, not a disability and certainly it is not who you are. Get a proper diagnosis, proper treatment learn to deal with your symptoms through behavioral intervention, and enjoy, perhaps you might stay away from air traffic controller, lol.
Not a simple answer. When we involve ourselves in something that we find to be fun, rewarding, interesting, etc., the brain circuitry system involved in not effected in adhd. So do something you enjoy. Also those with adhd tend to focus better if they are moving rather than sitting still, so find work that allows you to move around. It also helps to have a job where the surroundings are not too distracting.
