Is It Possible To Grow Healthy Ego Without Humans Around?

[SimpleGuy]

So as question goes, I`m reading now book "Six Pillars Of Self-Esteem" and author talks about how important quality of people around us, especially in infancy.

It makes me wonder, if there were no humans on Earth, could I grow up functional, healthy (in terms of psyche) ego? Sure, I would be bad at interacting with people, but in other aspects of my psyche - would they be fine? Maybe there`s some science on it. "How to become mowgli" ajaja

Also as an extrovert I started to really dismiss people and less interact with them because there are no one who even does self-dev.
