Jung published a book in 1921 where he coined and discussed the two terms.

It's not always easy to know when we're in the presence of "genius." In part, that's because we barely agree on what it means. In Roman times, genius was not something you achieved but rather an animating spirit that adhered itself to people and places.

The Swiss psychologist was born in 1875 and died in 1961. His father was a village pastor. His mother was a strong figure though she seems to have had a split personality.

Many people who don't know me ( Blaz Kos) that well or who only know my work from the media and speaking on a stage think that I'm a natural born extrovert - outgoing, optimistic, talkative, adventurous and always in action. The reality is much different, with me being an extreme introvert.
There’s nothing wrong with being an introvert. If you are emotionally unstable, being an introvert can become the biggest enemy of your progress in life. There’s a big difference between being an introvert and being afraid of public speaking, meeting people and speaking up when necessary. Social anxiety is not introversion, it’s a fear you must face and overcome.
