What makes someone an "expert?"
It depends on who you ask. Some people would argue that you can't be an "expert" on something unless you spent 12 years in university studying the problem, and now how have a bunch of "initials" after your name.
By that measure, I am NOT an "expert" on Inattentive ADD/ADHD.
On the other hand, as of this writing I am 52 years old and have lived with the condition all my life. So you can argue that I have "52 years experience in the field." And that certainly accounts for something. Would you listen to someone who's been avidly gardening for 50+ years if-- however-- they did not have a Ph.D. in Horticulture?
Two important things to keep in mind about this site:
1. I am not pretending to be an "expert" on anything, I am merely sharing my personal experience. These are not "how to" columns, rather they are my stories of "I did this, as a consequence of which that happened." I'm not saying it's gonna work for you, merely that it worked for me (or not!).
2. I am not pretending that this site is an "advice column" or a place that "prescribes" a specific healing methodology. I am not a doctor or a mental health professional. Again, I am merely sharing my personal experience, from living, breathing and eating "this thing," every single day of my life.
"Expert" is a bit of a nebulous term, in my experience. Somebody with a Harvard doctorate in business management will bring something different to the table than somebody who's been running a business for 30 years. Neither is necessarily "right" or "wrong." They are just different.
