Just finished my first year of grad school after a bunch of years working, so it's certainly been an interesting experience going back. --definitely get as much experience in your chosen field as you can beyond classes. For me, that was working at the student newspaper and being an active participant in the Humanities Club. I got my first couple jobs based on my writing and editing clips, not on any classroom work, and you'll also need to do something beyond the classroom to differentiate yourself from the other graduates for jobs. --There's no need to choose a major right away. I wasted a LOT of time and money thinking I was going to be an engineer and a teacher when i could have just been taking general ed stuff. --I'll probably get some disagreement on this, but pick a major that pays ok money. I just left a field of work I enjoyed in part because it doesn't pay enough. I discovered it was too idealistic to say "but if i enjoy the work, i won't care that it doesn't pay anything," because overall satisfaction is a combination of paycheck and job enjoyment. --Definitely take advantage of all the concerts, plays and lectures that are on campus, plus all the sports and activity clubs. They also make for a good alternative to getting wasted yet again. I've been doing all this as a grad (as an undergrad i chose 'wasted'), and I've been enjoying college life a lot more, plus meeting a lot of people this way.
