I'd quite like to set myself up as a contract florist spending all my days doing wonderful flowers for weddings and events. I'd also do lots and lots of photography and get really really good at it.
I'd love to buy a huge rambling house so that I could have loads of friends over to stay all the time and they could bring their children, instead of just keeping in touch via FB etc.
I'd also pay off my sister's mortgate, any remaining debts my parents have, help out as many friends and family as I could.
I'd like to set up some kind of charity providing really good quality cheap childcare for low income families.
Finally, I'd buy myself one of these so dh, ds and dd (when she eventually gets here) could sail around the world whenever we wanted to (avoiding perilous pirate infested waters of the Indian Ocean!)
