writing- social or individual?

I believe writing is an individual practice. I believe it is an individual practice because I write the best when I am writing on my own. I can only come up with ideas to write about whenever I am alone. When I am in a social environment I have trouble keeping my ideas while I am in the process of writing. I tend to lose my train of thought while I am writing when I am with other people. I think when you are writing individually the writing is more from you when you work alone and it is not affected by either what the people around you think or they are not fully your ideas, they could be someone else’s ideas. When I am also in a social environment I notice my work can be full of grammatical mistakes and also not make sense, I do not have this problem when I am writing alone. I think this happens because I take more time to think and focus when I am on my own versus when I am trying to write socially.
