I'm quite outgoing in my own right, but, strange as it might sound, I think I could easily survive as a hermit. When I am out in a natural setting, I am usually never lonely (at least, not half as lonely as one can get when one is holed up in a tiny apartment in a large city), because I see nature as something to communicate with. Add constant communication with God through prayer, and one gets a lifestyle where loneliness would be pretty much out of the question.
In a sense, it feels almost like an ideal lifestyle for me. Outdoors a lot, lots of manual work, natural setting, a life of simplicity without any troubling excesses, quiet, possibly keeping and looking after animals as well. That I do not have the calling to be a nun is another question altogether.
