Similar so far, but from what I gathered oh my expierience and others is that this is more of a long term productivity and overcoming procrastination sub.
Past version was more short term/ somewhat of a “booster sub”. With the new version, I suspect it will also be addressing deeper issues and beliefs, which would probably attribute to the fluctuations your noticing. Form of recon.
Personally, I am going to be making the exec the long term driver of my stack, rather then something I tack on at the end like the old exec/limitless exec
