It gives you some good methods but as the program says over and over it is not a panacea and requires a lot of work.
I think I've benefited from it but not as much as I'd hoped.
Also off-topic a bit, but for me, the single most impactful thing I have found for coping with anxiety is regular strenuous exercise. I'd been told this for years, but it's only recently that I've taken it seriously, and can now feel my anxieties begin to bubble up when I get out of my exercise routine. It's been so impactful that I just always want to make sure I highlight it when discussing anxiety, since it took so much time for it to really sink in for me.
My take-away from exercises was more of that it builds awareness that makes it easier to stay in flow states for longer over time, which in turn allows (like he says) kind of not making thoughts go away but getting less attached to them, also over time. It's definitely not an immediate gain, but I think the "noticing you are being distracted" and being able to stop is a good part.
