Johny Thundersbeard does not procrastinate about writing
Paint Your House. The outside.
When painting the parts of the house that no one will ever see (like roof side window sills on a cathedral ceiling); show great attention to detail and ensure all fiddly bits are perfect.
Join a department or project at your work that you think will give you lots of free time to write. Then quickly become the resident expert and go-to-person. Nothing will create a non-writing working environment faster then being indispensible.
