I get things out of my head as much as possible and it has helped me significantly. However, I tend to always have ideas that, at the time, don't seem that important to me and I immediately dismiss them. I do not capture them because I believe they are simply not related to anything that I am doing at the moment.
Does anyone else have these ideas and think the same way I do or is there some advantage of capturing these ideas even though you think they might not be that important? They are taking up psychic RAM, but is it really advantageous to capture them?
