I don't know how you define "HN" quality, but at the time of writing, the submission has 35 points. The post provides a great overview of how the author consistently succeeds at freelancing jobs that I found insightful.
I wrote the post because a friend of mine who is just starting to freelance wanted to know how I work. It's meant to be targeted at beginners and I agree, most people who have freelanced before should know most (if not all) of it. I do think they are still decent reminders, or at least I hope they are.
Anyways, I didn't expect it to hit the front page really but I guess some people are finding it somewhat useful/interesting.
