There is simply no substitute for hard work when it comes to achieving success.

I'd like to believe that achieving a leadership position is all about competency, capability and ambition, so I try not to distinguish between the sexes when it comes to giving career advice.

Starting early in life and in school, we need to ensure women develop the confidence and capabilities to work in a team that will allow them to reach the heights of leadership.

As a leader, these attributes - confidence, perseverance, work ethic and good sense - are all things I look for in people. I also try to lead by example and create an environment where good questions and good ideas can come from anyone.
