I'm not going to comment about OP, but I will say I've noticed that, in the majority of these posts, the person is self-diagnosed and has received no psychiatric evaluation whatsoever.
A significant number of founders may have "ADD"[0] in that they have trouble focusing, etc. This is like self-diagnosing depression based on the fact that they "feel sad".
I have no idea how many founders actually have ADHD - ie, DSM 314.xx - but I take any HN post about "ADD" with a whole heaping of salt. It's nothing personal, but let's just say that my internal Bayesian classifier has been trained to detect most as pure noise.
[0] I put this in quotation marks because the term has been outdated and deprecated for quite a long time in the medical community - in my experience, most people who say they have "ADD" haven't received any medical treatment recently, because that's not the term that any current psychologist/psychiatrist would use.
