These character traits are primarily learned, not innate. And no matter what your past or present, cultivating their role in your life can make your future bolder, more decisive and more successful. Courage is the ability to do what needs to be done, regardless of the cost or risk.
Integrity is the ability to do the right thing, no matter what the doubts or temptations.
A leader who can consistently do the right things, when they need to be done, is a leader with courage and integrity. The process of building courage and integrity starts with very small moments, out of the spotlight, where only you are there to judge. It begins when you first consciously exercise courage in the face of fear, when you first exercise integrity in the face of doubt. Like any other skill, your ability to perform is a function of how much practice you have. This practice compounds like interest over the long run and builds the stock of capability and internal resources you will need when confronting the big moments in your career.
