If you can’t change locations, then try changing your current space. If people distract you during the day, hang a sign on your office door (or outside your cubicle) asking people to leave you alone during certain hours of the day. If you need some energy and excitement, bring a radio or water fountain into your office for some background noise.
Taking a good long look at what your work style is can go a long way in helping you be more effective during the day. It will also help improve your mood and lower your stress level. If you’re in a space that’s perfect for you then you’re just going to be a happier person, no bones about it.
