I almost heard one of the most famous speeches in American history from a first aid tent on the National Mall.

On August 28, 1963, when I was 17 years old, my older sister and I snuck out of our house in Maryland at 6:00 am and traveled to the March on Washington, despite our parents’ objections. The day was hot and I hadn’t eaten anything. Standing in the front row, listening to the day’s first speeches, I fainted. The next thing I knew, I was in the first aid tent and Dr. Martin Luther King, Jr. was about to begin his iconic “I Have a Dream” speech. My sister and I rushed back out into the huge, alive crowd. It was a sight I will never forget.

Fifty years later, I listened to President Obama speak in the same place as Dr. King. I have come a long way since then – besides being lucky enough to have a chair this time – and, so has our country. Returning to the site of the 1963 March, it was impossible not to be moved by the sight of our first African-American president speaking in the same place that Dr. King had spoken.

My own story speaks to the extraordinary success of all those who fought for Civil Rights when I was growing up. However, it also reminds me that we have not achieved an easy pat ending of racial equality simply because we have our first African-American President as many on the political right would like us to believe.

I grew up in a military family – my stepfather was in the Air Force – which meant that my mother had to bring her own civil rights movement with her as we moved from base to base.

I started high school at a segregated school in Biloxi, Mississippi, where all girls in the 9th grade were not allowed to take science, and instead had to take home economics. After my parents went to the school board and got a special dispensation for me to take science, I was forced to sit in the back of a classroom full of boys. I still won the school’s science contest.

We then moved to Hamilton AFB in Marin County, California and lived on base. A little more than a year later my stepfather was transferred and since we could not go with him we had to move off base. The only area we could move to in those days was pretty dilapidated so my Mother repeatedly petitioned officials in the Kennedy Administration, and refused to move off base for months until my family was allowed to move into decent housing, which was in an all-white neighborhood.  Before we could move in, Air Force officials went door-to-door, checking to see if any of our new neighbors minded if a “colored family” moved in.  They didn’t – and ultimately, some of those neighbors became good friends.

In the last semester of my senior year in high school, we were transferred to Andrews Air Force Base in Maryland where I had to attend a newly integrated high school in Suitland, MD. I remember one teacher who was astounded that I had an aptitude for math and science. When I did well on my initial exam, she said in astonishment, “Oh, Yolanda, I didn’t know colored people could do math!”

Eventually, I built a career at IBM, worked for a tech startup and then started my own company with software I developed.

Throughout my career, I’ve known that none of this would have been possible if not for the relentless determination of my mother and the principled impatience of civil rights leaders like Dr. King and Whitney Young, Jr. As President Obama said on the anniversary of the March, “The arc of the moral universe may bend towards justice, but it doesn't bend on its own.” There were a lot of hands bending that arc.

Although I’ve come from being banned from science class to starting a tech company, from fainting in front of the Lincoln Memorial to working as hard as I could to help elect our first African-American President, I know that achieving Dr. King’s dream, and my mother’s dream, is still going to take a lot of work.

When my son got his driver’s license in 1993, my husband and I still had to give him “the talk” about being a young black man in America – the same talk my husband’s father gave him. And today, my friends who have young children of color must explain what happened to Trayvon Martin and why, heartbreakingly, they need to understand it.

Decades after my mother fought to get my family into decent housing and to give me an equal education, the income and wealth gaps between African-Americans and whites are continuing to widen. The unemployment rate for African-Americans is still twice that of whites. Our schools still provide a wildly different quality of education to children of different races. And even the protections for voting rights that were secured by the Civil Rights Movement were just torn apart by the United States Supreme Court.

Coretta Scott King once said, “Freedom is never really won. You earn it and win it in every generation.” When I hear that, I think of my mother and of the young people today who are now picking up the mantle.

The truth is that for all of us, the story of the progress of our nation is the story of our own individual lives. And in all of our stories, we have come a long way, but we still have a long way to go and therefore must keep fighting for economic justice, voter justice and educational justice.
