Let's Look at Latin

Cogito ergo sum  
I think, therefore I am
OR  updated and specifically:

1. I think, therefore I have a wee ache in my right shoulder
2. I think, therefore I overthink AKA worry and fuss
3. I think therefore, at 4AM I wake up wondering how life would be different IF I didn’t have Nf2, hadn’t shacked up with Stan, etc., etc.
4. I’d think but why bother, the republicans are going to take over and turn the country into a squalid, vermin infested Hell where only the ultra rich survive on the backs of the healthy but poor until none of us are left to be enslaved—then we die (unhealthy are left to die in the fields or behind the counters at McDonalds). Handmaid’s Tale didn’t take the story to its natural end. 

Dies irae
The Day of Wrath
This has been musically tricked out as a Gregorian chant. It would be totally appropriate as the hold music for:

1. Union of Concerned Scientists
2. Natural Resources Defense Council
3. Environmental Working Group
4. Friends of the Earth
5. Rainforest Alliance
6. Earthjustice
7. Ocean Conservancy
8. Earth Island Institute
9. The Sierra Club Foundation
10. The Nature Conservancy

Conversely it would work well in a dentist or investment banker offices. 

Carpe diem
Seize the day
We all know this from what was quite possibly Mork’s best movie. I’ll tell you what, on the days that I’m not in blinding pain (and I have much fewer of those excruciating days now) I totally carpe that fucking diem!

Alea iacta est
The die is cast
It's a war cry—the Roman version of ‘it is a good day to die.’
Commonly used in Vegas too.

Non compos mentis
Of unsound mind
Unsurprisingly this describes every last member of the death cult party AKA The GOP.

Veni, vidi, vici
I came, I saw, I conquered
Don’t know about you but I can’t help but read this as I wine, I wine, I wine. Preferably a nice Malbec or a lovely Pinot Noir. That’s just me? OK, never mind.

Acta non verba
Deeds not words
AKA Walk it don’t talk it—sound advice for every republifacist and christianist.
 
Totally unrelated:
Has anyone else noticed that Kenny on South Park always wore a red sweatshirt and died in every episode. Also, the Enterprise crew members who wore red shirts never survived the away missions. Interesting eh? I think I need to toss all my red tops. I’d bring them to Goodwill but that feels heartless and flat out wrong.
