Become someone whose word reduces uncertainty instead of adding to it.

Some people make a situation clearer by speaking and others make it murkier. Being the first kind means being accurate about what you know, plain about what you do not, and consistent enough that others can build on what you said. It is a genuinely useful function and there are fewer people performing it than you would expect. It also makes you difficult to replace.

After your next few conversations, ask whether the other person left with a clearer picture or a hazier one. Adjust toward the first. Reducing uncertainty is a skill and it is mostly made of restraint.
