Practice your English by watching this compelling talk from Facebook’s COO.

In this TED talk, Facebook COO, Sheryl Sandberg explores why there is still a huge gap in the percentage of women reaching top-level positions at work compared to men – and gives three valuable pieces of advice.

This talk inspired Sandberg to write her best-selling book, Lean In: Women, Work and the Will to Lead. Although she acknowledges that issues such as gender discrimination and sexism contribute towards inequality in business, she points out that women can be their own worst enemies when it comes to advancing their careers.

She believes that women frequently underestimate their own abilities and contributions in the workplace and tend to attribute their success to external forces, while men tend to credit themselves for their achievements. She also identifies another issue where women tend to ‘lean back’ or allow their work to slow down, as they believe that having children will affect their career progression.

In her talk, she urges women to:

1) ‘Sit at the table’ and have the confidence to make valuable contributions and pursue opportunities.

2) Share responsibilities at home with their partner so they can both pursue their careers equally.

3) Challenge themselves at work so that, when they have a decision to make in their personal life, there are compelling reasons to come back.
