Just about any creative-type person faces this demon. I know I do, I’ve been battling it all my life.
There are books about it. Libraries of books about it. There’s a whole industry about beating it. But it all boils down to one simple thing.
And this is it: don’t worry about the whole project, job, dilemma, whatever.
Just concentrate on the very first action. The smallest, simplest first step. Once done, then — and only then — concentrate on the next action.
One footstep at a time.
That’s all it takes. Don’t worry or even think about the overwhelmingness of the whole. Just take that first little step.
