I'd say college was the best time of my life -- undergrad years, that is. I'm in grad school now, and suddenly it feels more like a job, with "here, have this project, now do it indefinitely and work crazy hours." Undergrad is, you get there, you do your homework, you quit. Seriously. You go home for the night and get drunk/play video games/etc. all you want to. There is no obligation to work 8 hours a day if you don't have to. There's no need to go to lecture if you know the material already, or if you have a better way of learning it. Since you're not getting paid, no one cares if you decide to take a week off.
Most importantly: you get summers, Spring Break, 2 weeks around Christmas, and a host of holidays off. Just the first three total almost FOUR MONTHS of vacation. At my school, we also get all of January off, so that's five months, almost half an entire year without work.
Think hard about this: you will never have that ever again.
Ever.
I swear I'm not bitter.
