"Tell someone you love them today, because life is short, full of wonder and beauty. But because life is also unpredictable and terrifying, you should yell it at them, in German."
ICH LIEBE DICH!
I find most things are better when yelled in German. But Spanish works too. And Russian. Definitely Russian. And Klingon too, if you're into that. Any language where "hello" translates more literally to "what do you want" is worth constantly using loudly.
