My two dreams are either to be able to write, or to open a restaurant that serves tasty AND healthy food, that is so good that people don't realise it's actually good for them. The second is the big dream, I've spent daydreaming time working out the menus, and I know exactly where it would be, what it would look like etc etc. But I don't have the money to start it up.
So maybe if I had to be good at something for a year it would be poker or choosing lottery numbers or something like that, so I could earn the money to sustain my dreams for the rest of my life
