What is being said is less important than who is saying it.
People attribute credibility to the words depending on who is saying them.
So, if you want your words to be taken seriously, you need to build a reputation of authenticity.
To do that you need to spend your life keeping promises and delivering the goods.
A snappy tie and shiny shoes are meaningless.
Your actions are all that count.
Your actions ARE you.
You are the message.
