I went and it's the biggest regret of my life.

It took me 4 years to find a job after leaving because half of my prospective employers thought I was overqualified, and the other half said that completing university was no guarantee that I'd handle "real work". My first (and current) job is only tangentially related to my field and doesn't require a degree. Or any training, to be honest.

7 years before I bought my house, it sold for exactly half of what I paid for it. If I swallowed my pride and got a shitty minimum wage job straight out of high school, I wouldn't have a student loan (where I live it's interest free, but there's a minimum weekly payment which is based on your wage), I would have been able to buy a house so much earlier, for so much less money, and I would have been paying off my mortgage for so much longer.

In hindsight, my perspective is this: The actual cost of going to university isn't your student loans (which are still substantial, don't get me wrong) - it's time. Your degree has to make you so much more money than most people realise, because at a minimum you're starting your working life 3 years later than you normally would - that's 3 years you could have been working and saving, and 3 years of extra inflation to deal with.
