I really enjoyed reading this article, the quote below is a gem and I would agree that confidence is a large contributor to success. 

However the reality is it is impossible to feel confident about every decision you make and I can't think of a single person who's successful in business that hasn't had periods of doubt. 

But what we are talking about here is a that confident leader also creates a feeling of confidence in those around them which inevitably helps with the decision making needed to weather the sort of geopolitical and economic turbulence we are witnessing at the moment.

As the quote below says confidence has some close relatives but having confidence in yourself and those around you offers the best chance of success in the modern business world.
