It was extremely interesting and broke down/defined that there are 4 different personality types.
It had a quiz in it to help you determine which personality you fit into, however I think by reading below you can just about work it out for yourself

Soooooooo......what types of personality do you class yourself as ??
Here are the categories/definitions

Choleric: This is the commander-type. Cholerics are dominant, strong, decisive, stubborn and even arrogant.
A Choleric is focused on getting things done, but can run rough-shod over others. They are decisive and stubborn.
**Adventurous, persuasive, strong willed, competitive, resourceful, self-reliant, Positive, Sure, Outspoken, Forceful, Daring, Confident, Independent, Decisive, Mover, Tenacious, Leader, Chief, Productive, Bold.
Melancholy: This is the mental-type. Their typical behaviour involves thinking, assessing, making lists, evaluating the positives and negatives, and general analysis of facts.
A Melancholy is a highly talented person, they have brilliant ideas, although sometimes they can paralyse themselves with over-analysis. Lists and "doing things the right way" are characteristics of this personality type.
**Analytical, Persistent, Self-sacrificing, Considerate, Respectful, Sensitive, Planner, Scheduled, Orderly, Faithful, Detailed, Cultured, Idealist, Deep, Musical, Thoughtful, Loyal, Chart-maker, Perfectionist, Behaved.
Sanguine: This is the social-type. They enjoy fun, socialising, chatting, telling stories - and are fond of promising the world, because that's the friendly thing to do.
A Sanguine gets on well with people and can get others excited about issues, but cannot always be relied upon to get things done. They love interacting with others and play the role of the entertainer in group interactions. They have a tendency to over-promise and under-deliver.
**Animated, Playful, Sociable, Convincing, Refreshing, Spirited, Promoter, Spontaneous, Optimistic, Funny, Delightful, Cheerful, Inspiring, Demonstrative, Mixes Easily, Talker, Lively, Cute, Popular, Bouncy.
Phlegmatic: This is the flat-type. They are easy going, laid back, nonchalant, unexcitable and relaxed. Desiring a peaceful environment above all else.
A Phlegmatic is neutral - they tend not to actively upset people, but their indifference may frustrate people. They try not to make decisions, and generally go for the status quo. They care about people and harmony.
**Adaptable, Peaceful, Submissive, Controlled, Reserved, Satisfied, Patient, Shy, Obliging, Friendly, Diplomatic, Consistent, Inoffensive, Dry Humour, Mediator, Tolerant, Listener, Contented, Permissive, Balanced.
Of course there would be variances, but which would you mostly fit into
