I stumbled on this organizational system a few days ago and just had enough time today to take a look at it. It’s called the Bullet Journal. I’m in the process of browsing the web for a nice notebook with a grid layout so that I can try it out. I’ve used systems like this before, but I couldn’t keep up with it. Hopefully this one is different and more useful, so I’ll stick to it. Here’s a link for more detailed information and a guide on its usage.
