Everyone has some things that make them happy, things that remind them about beautiful moments in their lives... But why we keep them in boxes and just occasionally find these things and put them back?
As I thing, we should surround us with such kind of things that make us feel happy and warm. Don't buy home accessories just because they are considered to be in vogue. Buy something you really like, something that make you smile. Or, even better, DIY something with your family and place this object on a coffee table or on a shelf. Arrange your favorite books in a noticeable place; do the same with some photos etc.
I wish you good luck ;)
