Sometimes, saying nothing and staring at people is the best way to “improve your worth”. This makes people nervous, and when they’re nervous, they automatically need to hear what you have to say.

Say nothing, and look at them. Make them ask you questions. At this point, you won’t have to say much or expound on anything, and whatever you divulge, they’ll think is gospel truth.

Should they express doubt, it’s easy to answer: “You’re the one who asked. If you knew better, why did you ask me at all?”

I’ll stipulate that this is still “communicating” since inaction is a form of bodily communications. The best thing about this method is that it puts everyone on the edge of their seat, which leads them to value your input so much more than regurgitating facts with which everyone is already familiar.

If any of you doubt me, try it. I can tell you for a fact that Samuel Jackson does this on set.
