I use tagging heavily with any note taking application (like One Note / evernote). I use voice recorder to record any useful ideas / lessons that my subconscious brain tells me. I then push it to my note taking application with appropriate tag and push it to my cloud drive. I review them once in a while.

I am assuming you will not review them all but only the important ones. So you probably have a tag called 'important'?
