Sorry, but I think there is a little imperfection in your English expressions: "3.Pictureit" should be "schematize" or "visualize",
"4.Copy the experts" should be " Imitate experts".
I don't have the slightest intention of showing off anything, and I don't think I have anything to show off. I'm writing to avoid more newcomers being misled. I hope I didn't offend you.
