Why aren't you taking a Japanese language course instead of Latin? When are you ever going to use Latin? When you time travel to ancient Rome?

You'll miss these times. After college, it's a day in and day out rat race for the rest of your life. You think attending 3-4 hours of classes a day is bad? Try 8-10 hour work days, plus commute in heavy traffic, paying for everything, etc, etc. It sucks. Enjoy the easy life while you can. Get out and do something cool. Smoke some weed maybe. Take some risks. Anything you try in the future will have too many consequences or won't fit in your life.
