Never mind. It got rambly, and there was an ode to tea, and then there was a question, and my head hurts, and I'M ON VACATION AND STILL SICK AND THIS SUCKS!
Just remember: nouns are nouns and verbs are verbs, and they work so very well together, and sure you can verb a noun, but that weirds language. (In other words, no, happiness is a noun, not a verb. You can say Epictetus said it was a verb, but the only reference I can find to that is a "reinterpreted by" on Twitter, and that ain't contemporary, and that sure as shootin' doesn't give your bullshit meme of wrongness any legitimacy. And that sucks, because I was in the middle of reading a post about being kind to your body with food, a thing I need to work on, and that ambushed me, and there was a 15-minute interruption for a rant that got deleted for being rambly and off-topic and …)
My head hurts. *whine* (At least I don't seem to be feverish. Maybe.)
Wait, there was another thing! When you're defining something, you should define it using an equivalent grammatical unit. IOW, nouns should be defined by nouns and noun phrases, verbs should be defined by verbs and verb phrases. So to say "True happiness is a verb. It is the ongoing, dynamic performance of worthy deeds" is to be not only wrongsauce, it is to define a noun you're claiming isn't a noun by a noun phrase, thus undermining your argument doubly. *nodnod*
[Also, I didn't proofread this because did I mention my head hurts? So maybe there's a grammatical error easter egg for the finding.]
