I met plenty of focused/oriented people and depending on their field(s) of interest, environment and the presence of a spouse completing them, they manage well, or not so much.

What makes them that way? I believe we’re not born as “tabula rasa” and our minds are determined to evolve in specific directions from the birth. Some cite external influences, family, the possibilities the society opens, but then I point at the paintings found in Altamira or Lascaux and say “the external factors don’t matter that much”.
