This is a subject I often ponder on. My first novel - at least the first draft - was written almost completely whilst accompanying my husband on a long business trip abroad years ago. There was of course the added benefit that I was pretty much able to concentrate just on that, and not worry about doing the housework or wondering what to prepare for tea, but I definitely think that the change of scenery added a boost of inspiration.
Although the exotic tag-alongs are now in the past, I still try and do something on a (much!) smaller scale if I'm feeling a bit blocked, distracted or just blah. I follow the tried and tested method of many a writer and find a café.
Even though there's background noise (which at home I don't like), just the impetus of moving and putting myself somewhere else for an hour or so often gives me the push I need to get on and write, edit or just study something I've been meaning to for a while. And actually getting something done usually fires up the enthusiasm for getting more done when I'm back at home.
So, if you feel you're flagging a bit in the enthusiasm department, take a stroll or drive to a different location - it doesn't have to be a café - and see if the change of scene helps you break through the blah.
Does anyone have a favourite place they go to? I'd love to hear! Feel free to leave a comment below.
