There's no shortage of careers with fast-paced work environments requiring creative problem solving that would be well-suited to a person with ADHD.

Anything creative or artistic, healthcare, tech, sales, skilled trades, restaurants, etc.

If the "reality" you are trying to prepare your child for is becoming an accountant/banker/lawyer/bureaucrat, then you will probably all be disappointed.

Most people with a formal ADHD diagnosis are likely to require some medication in order to make it through the training for a career in healthcare. There is typically a lot of study and rote memorization required. Even a relatively simple job like phlebotomist requires an ability to focus and consistently follow fixed procedures without getting distracted.
