For most of my career, I've been the only woman in the room and at the table. Overcoming this obstacle started with accepting this situation as an opportunity rather than a disadvantage. I had to learn to stand taller, step up, speak up, and work harder so that my perspective was valued and my work was recognised. You learn to speak your mind and share your opinion as your experiences evolve. It also helps to understand the values of the organisation you are a part of. If the core values are inclusive and you make the conscious decision to live those values, it's easier for your voice to be heard. Luckily, this is easy to do at Salesforce.
I've also had to fight the stereotype that assertiveness and confidence in women are deemed aggressive. My advice here is don't try to please everyone, just be yourself and get things done.
I've also been in situations where people doubt my technical capabilities because I am a woman in a male-dominated industry. Above all else, always, always believe in yourself and trust in your abilities. Don't ever let anyone think you are inferior because you are a woman.
