Be transparent
Dembot: Top 10 Rocketboom Business Notions:
5. Be transparent. This is almost cliche now, though this is why it is important and should not be missed: Without disregard for being humble, the more you reveal, the more people will understand where you are coming from. It's not about blurting out some statement suddenly. It takes time to show yourself, who you really are. This motto applies to most aspects of life and business. The idea behind transparency is much more of a human personality trait. It's for you yourself and the people that you care about; It's for the audience that want to know when they ask; It gets to be that you no longer even think of this idea, it just becomes a part of your life-style. When you are fair, transparency will occur naturally because you will be proud and secure to reveal your true thinking.
The other nine are good as well, but I particularly fell for this one.
