Yay! You nailed it.
A couple of teeny-tiny comments (I’m being super-critical here, but you know me):
This is why professional copywriters charge as much as they do. -> this sounds a little like you have a hidden agenda. Not sure whether it adds to the content.
You did the right thing by following the rules of successful sales pages that you learned. -> Feels not as strong as your other sentences and it’s slightly confusing as “that you learned” refers back to “the rules” but isn’t mentioned straight after it. Perhaps something like: You did the right thing by following the copywriting rules you learned. And you’re nearly there.
you’ll be able to put it to -> you can put it to [shorter]
No course can teach it. -> this puts doubt in my mind why you could can teach it in this blog post?
Great job, Jonas! I like how it creates suspense at the end.
