Hey you. Yes you, lady in the black dress with hair tied up in a bun, do you ever have this tendency to think that when it comes to reaching for the top, you need to put in a great deal of effort just to succeed, or even just to get your work noticed? A lot of successful women—those who've gone ahead, and those who are ahead—know that climbing the positions of power and influence are especially challenging. But over the years, these same women—businesswomen, politicians, activists, entertainers, authors, role models, mothers—have defied the perception of society and have proven a hundred times over that men aren't the only humans who can shape this world. As part of the International Women's Month celebration, we give you 15 quotes from women shakers and movers, and their thoughts on leadership, success, and why we all need a woman's abilities to run the system. If you've been doubting you're prowess for the longest time, then these quotes can definitely encourage, push, and motivate you to reach higher heights—both in your careers and in life.
