ADHD seems to create the perfect storm for failure.
1) Accident Prone. Injured and not able to properly manage recovering.
2) Misses important details in most situations. Misses important opportunities.
3) Doesn't learn from past mistakes. Just keeps repeating.
It is heart wrenching to watch the people you love sabotage their success, relationships, future. Especially when they have so much talent, intelligence, and potential.
