What’s the most important lesson for improving your writing skills?

Steven Pressfield, author of The War of Art: Break Through the Blocks and Win Your Inner Creative Battles, reduces it to one short sentence and I agree:

Nobody wants to read your shit.

Let me repeat that.Nobodyânot even your dog or your motherâhas the slightest interest in your commercial for Rice Krispies or Delco batteries or Preparation H.Nor does anybody care about your one-act play, your Facebook page or your new sesame chicken joint at Canal and Tchopotoulis.

It isnât that people are mean or cruel. Theyâre just busy.

Nobody wants to read your shit.

And:

Whatâs your answer to that?

1) Reduce your message to its simplest, clearest, easiest-to-understand form.

2) Make it fun. Or sexy or interesting or informative.

3) Apply that to all forms of writing or art or commerce.

When you understand that nobody wants to read your shit, your mind becomes powerfully concentrated. You begin to understand that writing/reading is, above all, a transaction. The reader donates his time and attention, which are supremely valuable commodities. In return, you the writer, must give him something worthy of his gift to you.

When you, the student writer, understand that nobody wants to read your shit, you develop empathy. You acquire that skill which is indispensable to all artists and entrepreneurs: the ability to switch back and forth in your imagination from your own point of view as writer/painter/seller to the point of view of your imagined reader/gallery-goer/customer. You learn to ask yourself with every sentence and every phrase: Is this interesting? Is this fun or challenging or inventive? Am I giving the reader enough? Is she bored? Is she following where I want to lead her?
