This. Do the same thing, but with variations based on how badly I need to focus.

- First is a battered old internet-free linux box with a text editor and a few basic tools for focussed work / dev.

- Second is to sit somewhere unfamiliar in the office / home with grid paper and a pen

- Third, if something needs some proper, hardcore thought applied - hardcopy whatever I need, drive somewhere with a table (cafe, park, whatever), turn off all my devices and sit. Sit, read, think, write, repeat.
