How you decorate your office does say something about you and can be a conversation starter when unfamiliar people visit you, so it is worth considering what subtle messages you want to convey and the topics you are happy to discuss with strangers.

We spend a lot of time at work and research has shown that people perform better when they work in a pleasant environment, clean offices, with natural light, plants, comfortable furniture etc. (see, for example, http://smartbusinesstrends.com/tips-creating-healthy-efficient-positive-work-environment/) and are able to customize their work space to some degree. In fact, we see a lot of firms (Hubspot, Dropbox, Skype, Evernote, AirBnB etc. http://mashable.com/2014/01/09/playful-workspaces/) that design work spaces that reflect the company culture and often provide ‘play’ areas as well as quiet spaces to give their employees the freedom to move between different work environments that suit their needs and moods.
