1. Headphones or earphones?
Earphones. I'll never where headphones ever again. I remember the late 70's & early 80's versions far too well.
2. What is your "getting ready for a date" ritual?
I can't say that I have one. I just "get ready" in no specific order, nothing that I always do or anything. Depends on the specifics of the particular date.
3. Have you labeled yourself things (such as OCD, depression, bi-polar, ADD, ADHD) without a professional's opinion?
Nope.

Somewhere in the universe, they surely have to. As to here already, possibly, but I wouldn't bet on it.

Current: Starling Marte. All-time: Bob Walk. See what I did there

I'm fine with whatever length She wants her hair to be.
7. If you discovered an unknown land... what would you name it?
Joselunnd Atra.

Difficult to say. I've yet to learn of an existing legal system that I consider properly, completely fair.
9. Would you rather be the cheater or be cheated on?
Cheated on.

Not necessarily, but it certainly can be.

Several days; while camping.

Yes. I have my imperfections, but they're part of what makes me, "me".
15. Have you ever found yourself quoting a Disney movie?
I've done this, verbally and on various forum posts across the web, just to see if other people would spot the reference. Usually, they don't.

Moderately so.

Boneless meats. Meat cooks better and subsequently tastes better, when cooked while still on the bone.

Nobody specifically, off the top of my head. I'm more of a "find my own motivation" kinda guy.
