Edit 2: Questions 1 and 2 from the Adult ADHD Self Reporting Scale[0] (from Harvard, endorsed by the WHO) -
1. How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?
2. How often do you have difficulty getting things in order when you have to do a task that requires organization?
[0]: http://www.hcp.med.harvard.edu/ncs/ftpdir/adhd/18Q_ASRS_English.pdfArchitecture astronaut isn't a term for starting projects and not finishing them. It's a term for people who overengineer or overdesign their system.
Overengineering can lead to not finishing a project, but in the case of someone with ADHD that's unlikely to be the only issue.
Overengineering/Overdesigning isn't a problem I have, and is probably the single biggest thing I use to judge whether or not someone is a bad programmer, which is why what you said bothered me.
Edit: and even if I wasn't it wouldn't make a difference - flitting from one grand project to the next without actually completing any of them is a clear diagnostic marker anyone can read in a book.
