Just be sensible and dont let onto anyone AT ALL that you write. Try not to just hammer the same routes or areas. Jump on a train or get a mate to drive you to somewhere a little bit more built up then get a few hits up there.
The most important thing is to keep your house completely clean of flicks, sketches whether on your computer or not. Even after you have deleted a file off your PC it will still be there.
Goodluck mate.
