Yes, because when I first created them for others, I would wait a week before I’d send them to their owners because I wasn’t confident in my abilities, despite having created them for my children and seeing almost immediate changes/results.
I’ve also read several books, every tutorial on the forum and many internet resources, but I create them a little different than most people. The method’s given generally don’t vary that much but I have aphantasia and cannot make pictures with my mind, or even generate after images. So I used my own method, starting with my first servitor, which has similar aspects but is still somewhat different.
