If I think of something important, I will generally remember it for a long time. It's only things like errands ("What did I need again...? Oh yes, butter") that I tend to forget.

Not Great Ideas, no.
But faint echoes, suddenly noticed connections, things that 'ring a bell', yes, I can lose those. And I need to 'listen to faint signals' in teaching.
Think little used synaptic pathway glowing for 30 seconds then dimming...
So I have an A6 notebook and pen around.
I've found that as I've gotten older (and more busy) it's really important to keep notes. In my younger years I was more mentally agile and also more single-focused, and I got away with being not-very-rigorous with note taking (either digital or analog).
I've been keeping a "sparks" log (can't remember where I read this, somewhere on HN) where I just jot down small ideas for side projects, etc. when I have them.
Then when I have some free time, I pick an idea off the list and try working on it.
