If you have to work in the CBD in Sydney, and you live at any DECENT beach, I suggest you purchase this coffee cup:
make sure you put 2 hours worth of coffee in it.
You could live near Bondi or Coogee if you like tiny houses, needles and condoms on the beach, rubbish everywhere, and not sleeping at night because your neighbours are ALWAYS maggot. (oh did I mention they have bad surf and no kiting options)
