To me the topic title and the question posed in the poll are two different things.
I do enjoy solitude quite much. Not to sound like a sour grump or anything, but I just don't care much for most people (intellectual midgets, rude people, douchebags, you know the general population), and I would rather not be around them and just be at peace with myself. Going out and just wandering around alone in the forest, it's just so serene and whatnot. Also that's the sort of thing that I think of when I think solitude, not just being home alone - that's just TV time.
But then the question of is a significant portion of your time spent in solitude, it's just all quite subjective. A significant portion of time, what would that even be? I spend a significant amount of time sleeping, but that
time isn't significant. I don't go out much, but then again if it weren't for that then I would be headed down a completely different, likely less satisfying, road in life. So then it comes to whether or not I spend that time in solitude. Like Toma I'm another stinking artist, so I spend a lot of time honing my skills, and it wouldn't even matter if I was surrounded by a million billion people because when I'm working other people don't even exist.
Or am I not being literal enough? I know solitude is literally a synonym for alone, but in my dictionary solitude is closer to serenity (my dictionary has a lot of whiteout and added notes in the margins, it's awesome)
