I have found that it is much easier to write when you have a routine.
Mine is currently this: After work, go to the library.
Just like starting any new routine, it's hard to get into. At first, I'd stop for a cuppa, take a few notes or check emails before actually getting down to the business of writing. Now I have a drink in the office before I finish work, so that as soon as I leave I can head straight to the "Silent Study" zone.
It gets easier. And now, if I don't go, I don't have to punish myself because it's starting to feel wrong. I'm becoming more productive, having finished 2 1/2 chapters of Matti and 2,500 words for something else that is Three Sisters related, just in the last fortnight.
On a separate note, I'm off to the Edinburgh Fringe Festival for a couple of days at the beginning of August. Any recommendations? I've just finished compiling my usual matrix of shows I'm interested in. Top of the list is Paper Tom and The 90s in Half an Hour. Can't wait to get back to Edinburgh, if only for a flying visit.
