But then like, so then my parents said, okay, well, they got me on a diet free of artificial colors and flavors because that was the thing that people talked about back then. So I'm interested in this topic because I've come to appreciate now that I have many of the characteristics, if not, you know, full blown. It's like, I'm definitely time blindness, rejection sensitive, you

I don't know how much of that is based on inappropriate expectations, especially for children, and how much of that is based on true maladaptive kinds of tendencies. But what we do know is this, is that ADHD is associated with differences in prefrontal function, so that attention can be both moreβ€”you're more distractible.

You have a harder time focusing your attention on what's relevant, and so you shift too easily. But then once you get on something that you're interested in, you can get stuck. And so the attention is this beautiful balance of being able to focus when you need to focus and shift when you need to shift. And so it's that flexibility plus stability again.

And that balance seems to be disrupted in ADHD. And so as a result, memory tends to be poor in ADHD. But it's not necessarily because there's a traditional memory problem, but it's more because of this attentional issue, right? And so people with ADHD often will have great memory for the things that they're interested in and just no memory for the things that they're not interested in.

It's not like being a doctor or something where you have to be much more responsible and focused. You can just freely follow your curiosity, which is just great. But what I'd say is that I'm learning now about... so many things like about how to structure my activities more and basically say, okay, if I'm going to be, email is like the big one that kills me right now.

I'm just constantly like shifting between email and my activities. And what happens is, is that I don't actually get the email. I just look at my email and I get stressed because I'm like, oh, I have to think about this. Let me get back to it. And I go back to something else. And so I've just got fragmentary memories of everything, right?

So what I'm trying to do is set aside a time where I'm like, this is my email time. This is my writing time. This is my goofing off time. And so blocking these things off, you give yourself the goofing off time. Sometimes I do that. And sometimes I have to be flexible and go like, okay, I'm definitely not focusing. I'm going to give myself the downtime. And it's an investment.
