I found a method for this which works for me. I have a book labelled "Ideas & Inventions" and when I have an idea, I write down everything that suddenly hit me, and I keep writing until I feel I have exhausted the idea. If the idea then goes, I leave it in the book. If the idea remains, I write about it again, until, if it remains and I have to implement it, I do so.

Sometimes it will be a game idea (I've spent time as a game dev, the last idea cost me a couple of years & my family before I realised it wasn't worth it), sometimes it's an invention (electronics, mechanical, or both), and sometimes it's just an idea in general.

I find that the feeling that I have to make something is my way of preserving an idea, and to simply write down the idea often fulfils this need. And of the many ideas I write down, only the ones which really matter make it past the notebook phase.

Hope this helps others out there, and if you do try this method and find it helps, please let me know!
