Well, let's give the author the benefit of the doubt and try not to regard his article or its ideas in a subtractive fashion either; there's more here than the headline.
There's a lot of woo around meditation and mindfulness, but I genuinely believe that one of the most valuable habits I've acquired is just sitting still for a few minutes in the morning with zero distractions and observing where my mind goes.
9 times out of 10 it tells me exactly what it wants/needs to deal with that day, and if I want to stay emotionally balanced and pursue my deepest callings, I need to follow its suggestion.
If I don't do this I become out of touch with my inner state, less focused, less intentional, and over time, emotionally erratic.
The article's caution about doing this exercise if you have a condition like PTSD is very good advice, because eventually, the real shit you need to deal with will rear its head.
Everything you need for self-understanding and balance is there in your mind, speaking to you, all the time. Most of the time instead of listening we pull out our phones and distract ourselves. Or maybe we do what other people have told us to or follow some other drive.
But if you can and do set all that aside and just listen to the mind from time to time, it's almost a superpower. I suspect that many of humanity's greatest works have come about this way. Someone listening to what their mind just wouldn't shut up about, creating the conditions for hundreds or thousands of hours of flow state, and then just following its lead.
