Big Guy with a Booming Voice

I just got out of a meeting with a potential customer. The owner of the company was a big guy with a booming voice. He was not loud and obnoxious, but his voice commanded attention.

Why does it seem like so many business owners fit this description? Are these guys taken more seriously and respected more, or are they just smart? Do they have the commanding voice and then get the opportunity, or are they intelligent then develop the commanding voice?

I don't know for sure, but there does seem to be a correlation. I have seen research that suggests that both tall people and good looking people have more earning potential. I think the same applies to those with a commanding voice.

Unfortunately, I am short and have a very weak voice. I don't command much attention. Maybe I need to look into learning to command attention.
