Inspiration! Get the order right.
"Inspiration usually comes during work, rather than before it." - Madeline L'Engle
This was a HUGE lesson for me. Like many creative-types, I used to sit around waiting for inspiration to strike. I would write when I felt like it and then mentally whine about not writing when I wasn't, and the busier life got, the fewer and further between the inspirations came. Then I realized that if I didn't make time for it, it would never happen. That's why I now have set "writing times" that are about as sacred as they can. I'm accountable to it, because I've gotten a few others together to join me in my endeavour of writing regularly. It's so good for all of us, it's amazing the impact it's had! Just start working.
