It definitely has only bad effects on someone and can’t be used to positivity itself. It is the reason why someone does not end what he starts and does not focus on what he does, just doing everything without being focused and thinking about something else while doing that, so that applies to every area, be it during work or the non-professional life. It’s a disadvantage to live with. Everyone who has it, has a hard time to exploit his full potential and would be a lot better in everything if he didn’t have ADHD. Being hyperactive and at the same time having a hard time focusing on something is a bad mix. It’s like pouring oil in fire. It even is often the reason why people lose their jobs or are bad students and end up in jail. even if someone has high intelligence, he cannot use it to the full because of it.
