What matters is how you feel [Scott Adams].

I suppose that is a fact. I tripped over this quote in a book I was reading. Writing this now it is amusing to me that the title of the book is not memorable. This quote is. The title and next line are the whole quote.

Feel has a double entendre here to me. Feel physically? What do you think about “it”? What are the facts? Why are they facts and not opinion? Such a conundrum.
