Get a partner...i mean support

You want to get support for what you say or your ideas in front of your colleagues/co-workers or friends. Bring along a partner, a friend, a sidekick. When you have support, people are hesitant to talk you down because you appear strong and not alone.

Not too colorful...

Being subtly colorful in conversations is okay in the office. But being too colorful in character in the office will draw unnecessary or unwanted attention to you. It really depends on the job environment you are into. If you're a marketing person, then yes you would be expected to have a slightly more colorful personality. But, if you're a lawyer or accountant where boringness rules the day, being too colorful might make you stand out like a sore thumb.
