I’ve been a recording musician for 28 years. Making music a boring chore is not the answer. The best musicians do two things: learn to turn off the over-thinking part of the brain that blocks creativity and second, understand music theory in depth for when that fails and you get stuck.
I think it's more of a psychological trick for the author, and it would probably work for me as well. Some people are incredibly good at doing what they consider fun. Others have a hard time turning off the analytical/anxious brain and will never do something unless it's an obligation.
For me, I'm much better at getting bike rides and runs in if I'm training for something, so I "have to" do my saturday long run. Others would do this "fun" (hobby) stuff without prompting but have a very hard time doing their chores.

This is all pretty vibe-y but I think that might be what the post’s author found the ability to do and is trying to teach? TFA links to this other post in a similar vein: https://commoncog.com/get-numb-get-good/
