Well if you take up a trade you could potentially earn some good money, the first few years are hard graft though. I went to uni and made the mistake of not having passion for the course I chose to do, so if you do go make sure you are studying a subject you enjoy. The social side of uni is brilliant and I have met some quality people, and have done things I never would have done back home, like skydiving.
Overall it depends on you and what you want to do in your life. Uni is primarily about getting a degree, social side should come second, and there is no point in going just for that.
If I had to go back and choose, I'd still come to uni. I'd just have done a different course.
