I think most of out generation expects too much, are spoilt and want everything now.
Pretty happy to say I don't fall into these catergories however - it seems having nothing of value in regards to material possessions and growing up close to the poverty line taught me and my siblings life isn't easy, you need to work for your goals - they certainly aren't handed to you on a silver platter and your first care most definatly will not be a BMW - perhaps more to the point, you'll buy the bloody car yourself. Unless you are a millionaire, or marry one, you'll never buy a home in Sydney, based on your projected single income you'll never get a homeloan higher than $250, 000 - and you'll be renting for years anyway.
Also, $75, 000 pa and still living at home is digusting. I'll be offically out of home once I finish my EN's training and will be moving up to the Queensland. Renting, of course. Mind you, I reckon I know which town will be the next Mudgee, and considering homes have a current median price of $150,000 I'd consider looking into getting property there - then selling it when I want a place of my own.
