Apologies - I accidentally sent this without finishing.
Or that you're someone who simply finds this a smart and good quote, without any true meaning behind it.
I know I sound cynical! I know I sound like I could use a rainbow, or a good slap in the face, but when I see artwork like this (this meaning that it's a quote) then I get quite... I don't know what. It's simply that in my society the phrases "you only live once" or "YOLO!" Are used as an excuse to smoke (underage), drink (underage), take drugs (underage!), and have sex. (You guessed it, also underage.)
So please forgive me. I don't mean to sound like a grumpy guy, but... I think I've explained myself?
