Are you extroverted (E) or introverted (I)? Extroverts become energised when surrounded by people, while introverts prefer thoughts and emotions to activity and spoken words.

Are you intuitive (N) or sensory (S)? This refers to how you process information. If you rely more on facts and experience, you are probably an S. If you focus more on possibilities and have an idealistic mindset, you're likely to be an N.

The next indicator is whether you are a thinker (T) or a feeler (F). Thinkers tend to be more analytical, basing their decisions on logic and objective criteria. Feelers place greater emphasis on subjective criteria, and are considered more empathetic and expressive.

Lastly, decide if you are a judger (J) or a perceiver (P). Those who use judgment to organise their life enjoy making decisions.

Perceivers, on the other hand, approach life in a flexible manner and relish new experiences.

I would advise you to take all personality tests with a grain of salt, but I've found that most descriptions of the INFP type are fairly accurate as far as I'm concerned.

'But how does this relate to life?' you ask.

The answer is simple. You can gain a better understanding of who you are while benefiting from increased insight into other personalities.

Ever wondered why your best friend could never make up her mind? She's probably a P.

And she might be a T, if the reason for her indecision is because she's processing all her past experiences, whereas she might be an F if she's trying to figure out what decision pleases everyone else.

Personality tests provide useful information. But beware of stereotypes. People cannot be neatly categorised though they may seem to fall into certain groups.

So feel free to use the 16 given types as a reference point, but remember to look beyond the letters to see the person in front of you.
