Considering the job market at the moment, I'd say any higher education is a good idea.

Employers now have a huge pool of applicants to pick from, and they'll usually take someone who's better educated over someone who isn't.

Right now, you need every edge you can get over the competition.

College and university give you different things (at least here in Canada they do). College gives you more practical experience, more hands-on lessons and more of a grasp of the practical applications for everything you're learning. University here is much more theoretical. I took 5 years of Life Sciences (bio, chem, ecology, earth science, anatomy, physiology...you get the idea), and while we had lab work, reports, seminars and examples of practical uses for what we were learning presented in class, the lectures were just theory...lots and lots of theory. Same went for my sister who just got her university double-major in English and History. Our little sister is in college for police sciences, her classes give very little theory behind that they teach, they just how to make things work, not why they work the way they do.

Some fields favor college, some favor university and some require both. I can't really say for your field of study, but definitely research the qualifications for the job you want to get and see what they want. Do people with two degrees from college and university do better? If so, go to university. If not, then don't waste your time and money.

Well, I think that continuing your education after high school is a waste of time and money if you're not passionate about what you're learning. There's no point in going and learning something you're not going to benefit from... I went to school for a year for graphic design, and I didn't feel passionate about it after a while, so I dropped out. I'll probably go back to school when I think of something I'd really like to do... but if not, I see no point in wasting my time or my money on learning something I'm not completely interested in.

Also, like Talyn said, it would be good to further your education to get a nice job, because it's tough to find a job right now and I really think that having some qualifications like that would benefit you in the long run.

So yeah, if you're very passionate about what you're going to be learning, then I see no problem with continuing. Plus it will give you more things to lean back on if one career doesn't work out.

yes and no. find a job RIGHT NOW that can serve as potential experience towards the degree you are/will be working for. a degree is meaningless unless you have 3-5 years experience under your belt.

you failed to mention what area of art design you are interested in. if it is an area with ever-changing dynamics, i definitely suggest getting an internship asap and have them mold your schooling decision.

there is no way in hell i would go to 2-4 year university if i were studying web design (as an example). the market is too fast-paced and ever-changing for such a degree to remain beneficial. these types of fields usually require consistent education -- even through webinars, seminars, etc.

i cannot suggest strongly enough to seek out an internship or apprentiship as soon as you can in a field or market that can use your (present and future) services and skills. they will only have to sink money into you later for refresher courses and it may be more beneficial to allow them to sculpt you.
