I don't make a lot of noise about the work that I do as a business person. My mentor told me that being loud will always put me in trouble and working in silence and private means that not many will understand what you are doing or leak out your business strategies as well.
The only noise that is expected of you from your business is the results your business is bringing with a lot of success. When your business becomes successful, it's going to be making all the noise needed without you needing to do much except from your business advertisements.
