Actually I’ve been inattentive as a kid and when I like something time stops I can have really deep focus. But I’ve learn to dig subjects I don’t like to succeed at school and at work so idk if I have ADHD. Sometimes I really hate what I have to do at work and it can be really painful to engage with it and I procrastinate a lot. But I guess many people are like that

FWIW that is borderline diagnostic from what I understand.

The fact that you say "time stops" if it's something you want to, and the fact that you describe starting a task you don't want to do as painful to engage with and you procrastinate until you find some pressure to start…

I don't think this is necessarily everyone's experience at all.

And one of the problems with inattentive ADHD is that because it feels so intrinsic to us we assume it must be much like what everyone else must feel, and we don't ever question whether it is.

Another is that the IT world is absolutely rife with AuDHD and inattentive ADHD — people who canfind the puzzle in something complex, learn the hell out of it and then dive into it with unbroken focus until it is solved tend to earn a lot of money.

(How many tech people do you know who have three or four other talents or obscure hobbies that have huge potential value but remain to them underdeveloped while amazing others — playing an instrument they taught themselves, really good photography, woodworking, etc.; this is an ADHD pattern!)

And then when they begin to burn out in any given job, they confuse the burnout with structural failures of the job (it must have got worse) or with wanting a better job, so off they go to a new one, and unless you keep in touch with them over several job changes you never see the actual pattern.

The defining questions about a diagnosis are whether this pattern has negative impacts on the rest of your life. In my case… it definitely does. But I still have not sought a formal diagnosis because at this point it's just paying to be allowed to take medication I don't really want to take.
