@ZenHeathen I've become more aware of an interest fade in progress in recent years but no actual awareness of falling off the cliff. Things just get put down one day and never picked up again for months. Clutter blindness means I don't even see them during those first few not using months.
Then I see the thing, and might pick it up again right then or it's the kernel of an idea I should use it again soon-ish that may or may not grow into the yep gonna do this thing again.
Also, not official or self diagnosed ADHD but probably have some of that mixed with also not official or self diagnosed autism spectrum. Just .. Hey I see some of that in me, interesting, ok what's next.
