The silence is better than noise

A lot of loud people in the street, in train, in everywhere. Seems to be human specific .
But when someone want to do something, and it do it in noise, he has a small chance.
Great deeds is make in silence, with no interferece, without anyone knowing, in deep secretly.
Let's take an example:
you have a great idea, an idea who can make you a very successful man in business. But if you start to talk with everyone about that, someone will steal your ideea. And you will remain with dreams of what you could do.
But working in silence are better chance to succed. The silence is better.
     More than that, in all history many life was lost because someone could not keep quiet.
