A great writing resource is
The Elements of Style by William Struck Jr. and
E.B. White.
It's a short little book packed full with helpful tips, hints, and examples.
Here is one example of the types of advice listed in the book:
"
Exclamations: Do not attempt to emphasize simple statements by using a mark of exclamation.
The exclamation mark is to be reserved for use after true exclamations or commands.
What a wonderful show!
Halt!
Margins: Keep right-hand and left-hand margins roughly the same width."
