Ultimately its a life choice in my opinion.
I can afford to buy and run a 911 Turbo of some description - but I don't because it will mean I can't do many of the other things I like to do.
If you go to university it will mean a good education, a good time, a lot of hard work and potentially a better job and you have to pay for it later.
If you don't it means you work from age 19 ish or sooner and have to work your way up the ladder the old fashioned way.
