Sheryl Sandberg said this quote

I know that my success comes from hard work, help from others, and being at the right place at the right time. I feel a deep and enduring sense of gratitude to those who have given me opportunities and support. I recognize the sheer luck of being born into my family in the United States rather than one of the many places in the world where women are denied basic rights. I believe that all of us - men and women alike - should acknowledge good fortune and thank the people who have helped us. No one accomplishes anything all alone.But I also know that in order to continue to grow and challenge myself, I have to believe in my own abilities. I still face situations that I fear are beyond my capabilities. I still have days when I feel like a fraud. And I still sometimes find myself spoken over and discounted while men sitting next to me are not. But now I know how to take a deep breath and keep my hand up. I have learned to sit at the table.
