Personally I keep books and CD’s. I have lots from my teens and early adulthood. I like them, and I also like having a library that my kid can look through as he gets older. Clothes and furniture I’m not sentimental about though. Only keep what you’re actually going to use, sell, donate or throw away the rest.

Of course the water is free. And in many places you can get a free refill of coffee (Sweden).
