Can you guess what feature is almost universally common to bad writing? I'll give you a hint: it's a punctuation mark.
The semicolon.
When you find the need for a semicolon in your writing, you're probably attempting to bring order to a long and complicated sentence.
Don't give in to the temptation. Break your sentence up into parts, or better still, delete the sentence and start over.
Make a vow never to use semicolons and you'll remove one of the key enablers of convoluted writing.
