Let's see....
Legal advice. Before you post on a forum what's legal and what's not legal, look it up. Almost all laws and regulations are posted on the internet. Example:
www.copyright.gov
Someone earlier posted that trademark=copyright. Not correct. The differences can be found here:

Business advice. Do what you love, not what you think will make a lot of money. Do what you do better than anybody else can do it. Do your best to offer a product or service that nobody else offers.
Relationship advice. You have to give a little to get a little. Want to go to a convention or expo without getting any gruff? Take your lady out to a nice dinner the night before, or take her to a movie she wants to see (no matter what it is). This builds a cache of "do what the hell I want to do time."
