Hillary Diane Rodham Clinton, popularly known as Hillary Clinton, is probably one of the most powerful women politicians in the history of the United States.

Born on 26 October, 1947, Clinton served as the 67th US Secretary of State under President Barack Obama's administration from 2009 to 2013.

She was the First Lady when her husband, Bill Clinton was the president of the US from 1993 to 2001 over two terms. Besides, she also served as a senator representing New York from 2001 to 2009.

Recently, Hillary Clinton announced in April 2015 that she will be running for the Democratic nomination in the 2016 presidential election. Previously, she ran for the 2008 presidential election where she won more primaries and delegates than any other female candidate in American history, but lost the election to another Democratic candidate Barack Obama.

As she celebrates her 68th birthday today, here are some of Hillary's inspiring and influential quotes that make her famous:  

"People can judge me for what I've done. And I think when somebody's out in the public eye, that's what they do. So I'm fully comfortable with who I am, what I stand for, and what I've always stood for."

"We must stop thinking of the individual and start thinking about what is best for society."

"In almost every profession - whether it's law or journalism, finance or medicine or academia or running a small business - people rely on confidential communications to do their jobs. We count on the space of trust that confidentiality provides. When someone breaches that trust, we are all worse off for it."

"The worst thing that can happen in a democracy - as well as in an individual's life - is to become cynical about the future and lose hope."

"There is a sense that things, if you keep positive and optimistic about what can be done, do work out."

"If a country doesn't recognise minority rights and human rights, including women's rights, you will not have the kind of stability and prosperity that is possible."
