Teaching myself about "The Grid"

I have decided to teach myself more about the Grid as i feel like it is one of the more imo=portant skills of graphic design and can spill out into other areas such as=s logo design, web and print. I will practice my layout skills every sunday while reading up on the subject. i will do some experiment in laying out existing articles and see if i can develop my skills. This week i read up about the different types of grids and trolled through my books and magazines to see if i could determine what type of grid is used.
