A question about meditation with an ADHD mind. I've meditated, on and off, for several years now. For years I tried to sit staring at the wall, following Zen Buddhist tradition. While I don't have a problem with the actual sitting, the restless monkey of a mind has been a struggle. I've finally understood it's easier for me to concentrate on the moment when there's a constant change in visual input. The best so far is looking at ground while walking.
The part I'm struggling the most with is noticing the current thought and letting it go. For me, it's a sudden shift in perception: I don't usually notice the current thought but instead remember now, which then pushes the previous thought away like a flick of a switch. I might even forget the previous though. Any thoughts or tips regarding this?

mine isn’t necessarily the most correct one, but it’s the one that works for me after trying several others. And why this one works for me: it reduces inner judgement and over-analyzing during meditation, so it brings me more to the present moment with added calmness. Especially if you don’t even remember the last thought you had, it might be useful for you too. It’s okay that the thought came and went, whatever it was, that is what thoughts do.
