That’s a long article. I didn’t fully read it. But I agree with the idea to reject pessimism. If there nothing to be optimistic about, you can at least not be pessimistic. Why? Because it sucks to be pessimistic. And also, moping has never helped anybody. We learn that as kids, but we seem to have forgotten that as adults.
As a quick remedy for acid reflux, I recommend Marie Biscuits or Rich Tea Biscuits. They kind of seem to absorb the acid reflux… I don’t know how it works, but I always used to have a pack of those Biscuits in my bag when I used to have regular acid reflux. They worked very well for me. Of course, changing my diet and lifestyle worked much better and now I haven’t had acid reflux in years.
