The Golden Rule

When you want the readers to know something about a character or scene don't say it, show it.

Instead of saying, The sky is blue, say it in more detail; she gazed up. the perfect combination of blue and white. it lit up her eyes.

Another example of the golden rule.

Alex likes Mallissa. WRONG

His thoughts spun around him like a carousel. Does she like me? Does she feel the same way? Does Malissa even know me? CORRECT

See the difference. If you are always explaining everything as a narrator then your readers won't be interested and eventually get bored.

Follow the Golden Rule. Show Don't Tell.
