Sally and Jim don't get along because they don't understand each other. Sally is a photographer. Her bedroom's a mess, and she's usually at every party. Jim, on the other hand, color-coordinates his file folders, spends a lot of time alone and is studying to be a lawyer. Talk about a personality clash. Thankfully, there happens to be a really effective tool that explains why people are the way they are.
Epipheo shows you how the Myers-Briggs Type Indicator (MBTI) makes it easier to understand yourself and others.
