A writing tip I wish I was taught in school

Someone introduced me to a way of writing that he was taught in school. He suggested that I write a draft of my blog post first, just for myself. Then read the draft and make any necessary changes. Then repeat the process again at least twice.  

Even though he didnt mention it, what he said also gave me an idea to hand write my drafts in my notebook. Each time Id type the draft from my notebook. Then when it seems okay I’ll publish it. I noticed trying out that writing process he introduced I’m omitting things that wernt needed in the post. Like there were some things I had in this post I’m typing now that wasnt really required. 

It’s kind of tedious. Though I think it’s a good idea.
