Some can. Others end up in jail [0], or dead [1]. I wouldn't want anyone to assume that if they have ADHD, they automatically have access to some sort of super power - it doesn't always work out like that.
Like you though, I do try to harness this as best as possible for work. Music works quite well as an aid for me too.
