Randy Murray, in his excellent post today, “When You Have A Burst Of Creativity, Go With The Flow”:
It doesn’t matter if you’re a writer or a baker. When the mood strikes you and you find you can suddenly make things happen, do everything to stay in that mood. Create, build, bake. You can always rework later. You can go back to your plans, if you need to. It probably won’t last long, but when you can just let the ideas come and let the work flow, you’ll likely find some things you didn’t know you could do.
This is why having the ability to capture ideas wherever and whenever they come to you is so important. Often it’s not just the idea that is sparked, but along with it come three or four other pieces which all get connected at once and you have that Ah-ha! moment.
