During a period in my life in which I was having a bad time, I decided I didn't want to deal with anyone or anything. I stocked up my apartment and didn't leave for almost a month. I didn't turn on the TV or stereo. I didn't have a computer. I let all phone calls go to my answering machine, and only returned two or three to my mother so she wouldn't worry. In some regards, it was one of the best times in my life. I did some thinking and learning about myself, more than I've ever done before or since. I realized some huge mistakes I was making in where my life was headed. My acting improved tremendously after this, as I learned to tap in where my thoughts were actually coming from, rather than where I thought they were coming from. I know that probably doesn't make any sense, but I can't describe it any better. I did find myself talking to myself a lot, it rose to the point I was narrating my activities to myself. I stopped when I realized this was starting to cease to be a voluntary activity on my part, that I was starting to prefer my own company to others, and that this was starting to become irreversible. I am a lot more comfortable now, as I know myself better and know I am fine alone with myself, but I don't recommend it for a long period of time for anyone, and although I would be OK with it, I don't see it as a preferential option for myself.
