Can not the space between heaven and earth be compared to a bellows?

It empties itself, yet it does not lose its vigor;
If moved again, and behold, it expels air once more.
A lot of talk, to rapid exhaustion we see lead;
Guard your inner self, and keep it free.

— From the Tao Te Ching, part 5

The hard thing is not to write every day. Anyone can write, just as anyone can speak. The hard part is to hit the keys (or open your mouth) and make something worthwhile come out. “Idle writing” is where many stumble.

The writer has to expose his or her inner self. They risk being misunderstood, or sometimes even worse: being fully understood, and judged inadequate. But to do anything else? That’s idle writing.
