Ouch is right! But hold on, where do you put your money that you get a consistent 8% yearly interest rate? Because I want in!
It's true though, college is not the right choice for everybody and there is still a stigma attached around not going to college.
My biggest financial mistake is not saving more. Similar to yours. I had decent income throughout college and straight after.
I saved a bit and was able to part-fund my postgraduate degree. But I could have spent less on crap I didn't really need and saved a lot more. This would allow me a lot more financial freedom right now. As you say, hindsight is 20/20.
