I'd most like to (personally) explore:

Death can come for you anywhere. One day, walking through a cross walk in a major city during the middle of the day, I was nearly hit by an asshole driving around a corner too fast in a very nice BMW. I jumped out of the way just in time but the car hit my groceries.

Live your life. Take reasonable precautions like having a guide take you through the jungle, or going with an instructor if you try something dangerous in the beginning, like rally racing. But always live your life, like today was your last day. The world is on fire, and we never know how long we have left.

(Although in fairness we didn't start the fire [youtube.com])

But always live your life, like today was your last day. The world is on fire, and we never know how long we have left.

Bad advice. If you live life like today's your last, you'll act without consequence and without concern for the ramifications of your actions. It's one of the reasons I hate that term YOLO (You Only Live Once) - it's basically a passport towards dangerous and counterproductive behavior. People need to learn how to think long-term - we've got enough problems in the world due to short-term thinking fucking up things down the line.

Of course it's all about balance. Don't be so concerned about things that you won't take any risks. Just make sure those risks are measure and that whatever you end up doing doesn't end up hurting yourself (or others) later.

I like the advice I heard from an economist on a Freakonomics podcast when asked by a teenager what economics can teach us about romance(specifically with regard to asking a girl out to prom).

The economist starts off by admitting he doesn't know anything more than anyone else on romance. But he suggested that many people suffer from "loss aversion", a tendency to strongly prefer avoiding losses to acquiring gains( http://en.wikipedia.org/wiki/L... [wikipedia.org] ). The young man was afraid of rejection, which might sting briefly, but will likely have minimal negative impact and likely no long term impact. But if she says yes, he'd have a date to prom and a memory of prom he can look back on for years. The guy was just focused on the possibility of rejection.

Unfortunately, "Reduce your loss aversion" isn't as catchy as "YOLO" or "Carpe Diem". But it's more practical life advice for many people.

The main difference: "carpe diem" is for intelligent people, but "YOLO" is for idiots.
