@sometime sun,
I spend a fair share of time alone, both out of doors and in. I don't, however, behave in any way like a hermit.
Thinking and learning about the world is an occupation best pursued alone, I am more observant when alone.
On the other hand, I learn as much from other people as I do from my solitary observations, it is ,I think, important to strive for balance between my social life and my solitary life.
