One thing some aspiring and many established authors forget to do is
And "smell the roses:" to live life, to garner new experiences, to step outside the box, etc.
In other words, leave the writing alone for awhile--it'll keep; life won't.
I've been catching up on yard/housework, taking care of family business, attending my cousin's wedding, listening to concerts in the park. I needed to do these activities, but more importantly, my Superior temporal gyrus (the section of the right brain where creativity is thought to spark) demanded a break.
I take a 'brain break' by working in my meditation garden, and this has been the result:
Other flowers will bloom after these are finished, so I will always have something of beauty to gaze upon, appreciate--and take care of. Just like my writing, there are times you simply have to enjoy something but turn your attention elsewhere. My garden doesn't need me now, but my writing does.
Need a fresh angle? Stuck on dialogue?
While you're mulling over the writing obstacle you're facing, do something else and let the solution come to you. (It will!).
I'm headed back to the writing cave, but I know this afternoon, I'll take a break and after some laundry, I'll be here:
Go enjoy a mini mind vacation.
