Going to give this a try later. I've had the same experience, and every time hit a point of going "I'm X levels deep in syntax I don't understand and can't see a benefit in sight..."
I'm currently reading Graham Hutton's "Programming in Haskell" (2nd), which is also another great resource. He also has YouTube videos [1] for chapters in the book. Philipp's videos are great too, which I also watch after finishing a book chapter.

It is incredible. He does an amazing job of starting from the basics and then diving deep. After going through the series I had a solid enough grasp on the language to use it for practical things.
