Sorry but I disagree. Money can buy happiness but it can't buy contentment, which is much harder to achieve. I know incredibly rich people who are very happy in their huge homes with their fast cars and fancy holiday homes, but they never seem to be content, always needing the next new toy to play with.
A really good gaming PC (I dropped mine and broke it this morning)
Lots and lots of lovely shoes that I will never wear because I don't go anywhere.
Pyjamas... I have a bit of a thing for wanting/needing lots of PJs. :)
