I don’t know, I have thought about it a lot. I am alone (with a kid). I have always seen I do more work when I am alone. But in that time in my mind, I stay little unhappy. But when I a surrounded by people, they take more time from me and my work processed very slowly. Though they disturb me in my work, I like to have them. So, in a conclusion which type should I choose? Don’t know. May be I have to choose both randomly.
