The writing that's the easiest to read is the hardest to write.
- Avoid cliches. Instead of saying "She's pulling her hair out!" say "She had clumps of eyelashes between her clenched fingers."
- Use colorful language. Say things like "Vivid pink splotches danced over her computer screen late at night, like Pepto Bismol for her eyes."
- Conflict is all important. "She ripped the spine out of her thesaurus when it refused to give up its secrets."
- Show, don't tell. Instead of telling the reader "She was losing her confidence as a writer," let them discover it themselves: "Her stiff neck could hardly support her head as it drooped under the weight of leaden ideas, too dense to express in a drizzle of words."
- Don't be afraid of being too obvious. If your character is scared, for instance, don't be subtle. Say, "She rubbed her churning stomach, wondering what would happen when she vomited chunks of her heart."
