For me the best insperation is sitting in front of my pc(the envioroment im gonna be writing in) and listening to some great techno or whatever and getting in the frame of mind I need.

After an hour I find myself full of ideas.

Ive found myself with a bit of a block over the past few days at a piont where im realy needing too find that vibe and just couldnt.
I found myself binning around 5 or 6 attempts last night but thankfully today somthing I started was pushing my buttons so I had more or less forced it.
I felt like shit for the past few days untill I got somthing I was happy with.
