How you work affects your personality

Can what you do for a living actually change who you are? We generally think about personality as relatively stable over time (and it is). But then again, personalities can change. Especially with experiences that are repeated, day after day and year after year. Researchers recently published a study following a large group of employees over the course of 3 years, while repeatedly measuring their personality and working environment. They focused on a set of traits called proactive personality.
