It was interesting and a fun read, but not a “good piece of writing” in my opinion. Apart from some spelling mistakes, the sentences droned on and it read more like a semi-coherent rant than a thoughtful piece on “being a pop star”.

I thought it was excellent for something that appears mostly off the cuff. This is what lots of good writing looks like before the editors get to it, btw

It is thoughtful, that's not the problem. It's just not written in the standard language "written English", but instead in "spoken English" with some attempts towards the former ("My final thought on ...") that sound like someone trying formal writing for the first time.

The sentences do drone on, but they're fully coherent; this is above-average writing. It wouldn't likely meet publishing standards, but it's a lot better than you'd expect a randomly-chosen person to produce.

As interesting as I find it, cannot agree more. It's very childish writing - feels a lot like it was written by a teenager. It sort of reminds me of my young 8 year old niece telling me a story she finds so exciting she barely comes up for air.
