Take your time and groom yourself, take your timer and arrange everything on your desk. That dust, those hanging cobwebs in your study, and the multiple yet to be shelved files that you keep around you all the time are not required.
All you need are concrete writing plans and schedules. Decide on the projects you want to work on in the next few days or weeks and get down to business. Forget how everyone else with genius behaves and just be yourself for a single day, stop finding influence in the wrong company by thinking that only by drinking alcohol like fish would water can you get your act together.
you can write pretty good stuff if you put your mind to it. But part of the discipline required in becoming a great writer is organizing yourself physically, mentally and emotionally.
