Most of the time I play alone on my pc , listening to music or watching a good movie or rarily a tv show or a video on internet a lot of stuff on youtube .
I play evening or night , so I switch on the lights and I open the window for fresh air so as not to get sleepy or tired when I play tournaments .
I do sometimes going to a internet cafe and playing there poker as I enjoy the social environment as someone said before , and then my performance gets better , in spite of the fact that there it's not as quite as in my room , but I like it very much .
