Soft skills are vital for women to succeed

The ability to lead without authority, meaning “being able to drive change when you have no authority or say, trying to persuade [others] the reasoning and the impact the new change is going to have” is a key skill. And that skill goes with building relationships: “You can’t make those changes if people don’t trust you.”
