(This is a modification of something I originally wrote in reply to a teenaged girl. Obvious?)
I know school has taught you that learning is totally uncool, but surely there's something you're interested in. Go memorise the details of every Yu-Gi-Oh! card or whatever.
Fine, you're bored. There's nothing you can do about that. May as well learn French. You're bored whether you do or not, and if you learn French, you can go tell your parents 'Look, I taught myself French. I'm all grown up now so you should let me go to Paris. By myself.'
They'll say 'No, you're too young to go to France by yourself. Here's two tickets. Take your best friend Jill with you.'
So you take your two tickets and your best friend Jessica, and fly to Paris, where you meet enough hot French boys to keep you busy all Summer. Then, while you're there, you meet Johnny Depp, and he's really, really impressed that you're bilingual, so he marries you and you live happily ever after with the sexiest man alive. (Jill ran off with Orlando Bloom.)
What? You think it's awful that I'm telling you how to run your life? Maybe it is. But who cares? Are you going to give up a happily ever after with Johnny Depp just to spite some random jerk on the Internet? Or are you going to marry that sexy pirate captain-playing actor and become the envy of every creep on the Internet who is still stuck monolingually telling random people online how to live their lives?
