Mental focus

I just noticed how much effort I put into remembering what I was thinking—I do a lot of “I had an interesting idea about that which I wanted to include—what was the idea?”.

It can take at least 3 or 4 repetitions before the idea finally gets typed out, partly because I might be typing or formulating something else and then want to get back to an earlier idea.

I’d be amazed if I were the only person here with this problem. Any suggestions? Does dual n-back help?
