This is easy! Learn to use the computer! Of course, my younger writing self didn't have access to a computer - it was years before it was made available for the average household. The Internet has opened doors never thought possible and that pertains to writing books.
For me, it's vanity publishing. I know some writers might think it's a great way to get published, but it's a money-making scheme. It's much better to just go self-publishing and do it yourself and make way more money and have all the control.
I suppose I have been writing since the day I discovered a pencil and a blank piece of paper, lol. My earliest recollection was in 2nd grade when my teacher asked us to write about our summer vacation. Instead of the usual way, I suppose I wanted to do something different but I took unlined sheets of paper, folded them in half, punched three holes in the side and ran yarn through the holes to hold together my 'handmade' book. I can remember even back then how neat it was to have the title and the name on the front and of course I illustrated my tale of my favorite vacation - Long Beach, California.
