How to Write Well

1. Avoid alliteration. Always.
2. Prepositions are not words to end sentences with.
3. Avoid cliches like the plague. They're old hat.
4. Comparisons are as bad as cliches.
5. Be more or less specific.
6. Writers should never generalize.
Seven: Be consistent!
8. Don't be redundant; don't use more words than necessary; it's highly superfluous.
9. Who needs rhetorical questions?
10. Exaggeration is a billion times worse than understatement.
