Introversion (noun)

The state of being introverted; the tendency to be more interested in one's own thoughts and feelings than in external things or other people.

Origin:

From the latin introversus, from intro (inward) and versus (turned).

Examples:

1. Introversion is one of the two major personality traits in the Myers-Briggs Type Indicator (MBTI).
2. Introversion is not the same as shyness; introverts can be sociable, but they need time alone to recharge.
3. Introversion is not a disorder, it's just a personality trait and everyone has their own way of functioning.
4. Introverts tend to be more reflective and contemplative than extroverts.
5. Some careers may require more or less introversion or extroversion depending on the nature of the work.
