This is a great question that can be answered with many answers.
Simply, and as cliche as it is, it is to believe in yourself and promote your true self. Simon Sinek wrote a book called "Start with WHY" and it is about finding out WHY you do things and start with telling people why you do things instead of what you do.
Mostly everyone promotes WHAT they do and HOW they are different from everyone else who does the same thing they do.
I firmly believe Sinek is correct when he says to start with telling people WHY you do what you do then tell them how you do it. Once you start to apply this to everyday life, you will notice yourself become different from your peers. It will be subtle but this is a way to stay true to who you are and what you believe and you can be a leader with that.
