I tend to isolate myself from the internet in a coffee shop and drown out the outside world so I can completely absorb myself in the writing. I listen to a lot of electronic music, because if I hear lyrics it removes me from concentrating on other words, or any verbal train of thought I'm having. How about you guys?
I don't like music. I can write anywhere, anytime and best under pressure. The only exception is writing something deeply personal which I usually find myself putting off, instead of delving immediately into.
