If you are a coffee lover find a small unused space (or under used like many living and dining rooms) and create a custom coffee shop in your home. Coffee/tea is an art form for those who treat it as a ritual so make it a special part of your home.
I want to open up my own cute little Cafe when I'm older. I have always loved Cafe's and I'm motivated to open my own up. It would just be something simple, and it WOULD serve certain foods, like the Koffee Kuppe (It's a cafe that I loved when I was younger. I lived by it).
