I finished college in May when I was 18 and moved out around about July time with my boyfriend at the time in another city. It took until the November to find a job so it was difficult, especially being on my own two feet away from my mum.
I moved back in with mum after a year and got a house after three months, two doors away from my mum (really regretting that now...) Hoping to move out as soon as I can. The house is far too expensive for a one bedroom.
I was nice enough to keep my mouth shut when I met my friend who said I'd fail at life because I didn't go to uni. He's been out of uni for a while, is in shit ton of debt, no job and still with parents.
EDIT: Nothing wrong with living with parents. Rent and bills is a pain in the arse, I'd rather live with them >.<; but you probably shouldn't be arrogant and assume Uni will guarantee you a job and everyone not at Uni will be stuck working in McDonalds or something.
