Travelling. It sounds so great on paper but the reality is often the opposite. In fact I enjoy the planning, research, googling the maps etc. far more than actually travelling to a place and being/getting there!
Giving up work, selling house and travelling (that word again!) around Europe/the world in a camper van. I mean who wants to live in a sardine can where you'll hit your head every time you move, the toilet is in the kitchen or in a bush, the water is scarce and you cook beside your duvet, on the bed that was the table. But it is SUCH a lovely idea.
Same thing, except instead of a camper van, move to a run down charming little house in a tiny village in Italy/France/Greece. No plumbing, no electrics, do it up in the unrelenting heat, can't get tradesmen, the floor collapses, the money runs out.....
So I'm a home bird but I romanticise about having a maid/housekeeper though.
