How to successfully negotiate a deal when we are a woman?

finding the middle ground in negotiation

Your gender only plays a role if you allow it to.

In the first place, nobody asks you to negotiate yourself. You can send a professional negotiator instead to do this. Various high-level universities and business schools offer courses on negotiation.

Truth be told, your gender has nothing to do with how successful your negotiation will be. The key to success is showing that you understand your counterpart's interests and connecting with them.
