If it's a paper asking your opinion or ideas on something, then I used buy a 6-pack of beer, sit down to write paper with some good music on, and just drunk write for about 3 hours. You'll suprisingly write like 17 pages of bullshit and ramblings, but after you sober up, you can typically condense it down to about a solid 3 or so pages of legitimately good ideas to build off of. I used to love writing papers as I essentially made an event out of it.

Once I figured out my groove, I stopped the drinking and discovered that isolation was always key for me. I had to find a space without distractions. Our school library had a floor with hidden tables, rooms, and a rule that no talking was allowed. It was dead silent there....it was fantastic.
