I would caution not to get paralyzed by perfection when it comes to content. From the first publishing to the 100th, you will make such progress in quality, you will probably wonder why you delayed at all.
That's quite true. I started training already with my own account and it's true that it's getting better with every video.
The biggest challenge at the moment is to create content together because we live in different countries and both have some time comitments. We need to find the magical formulae that works for both of us :-)
