Narcissists demand your undivided attention, and your complete devotion, which can be quite seductive to start with. But soon you realise that it’s suffocating.

Narcissism is part of the Dark Triad. The other two traits are Machiavellianism, and Subclinical Psychopathy.

The opposite of this is the Light Triad, which is group of three core traits capturing the essence of a positive personality. These are Kantianism, Humanism and Faith in Humanity.

Flextroversion is associated with lower levels of stress, depression and anxiety. Flextroverts are also physically healthier, more tolerant of other people and better at coping with change.

Flextroverts don’t rely on habits and routine behaviours, they are open to new experiences, and they are willing to take risks to make meaningful connections with others.

You can become more flextrovert by challenging yourself to do something different each day or each week.
