Be clear in your communications

Do not worry about how short your speach is. What matters is how clear is it.

Another learning is that bigger the audience of your communication is, crisper the communication should be. If you start to dwelve into too many details, in a short speach to a large crowd, it will create a lot of confusion.

Keep in mind that your main message, whatever you are there for in a place, should go through. Rest, doesn't matter.

Unclarity in communication, or using indirect language, may lead to suspicion and in-turn to dis-trust. The behavior shows up as if you are hiding something. What ever you know, communicate that very clearly and crisply. Tell about the rest that you don’t know.
