Her winning speech was about speaking up. In an interview, she wrote:
The theme of my speech was to speak up. People sit in silence so much afraid to express themselves and it often diminishes the quality of their lives and those that they love. The fear people have has to be overcome and the purpose has to be the passion.
I chose this theme because growing up, I saw so many people abused because of their silence. I witnessed people be broken because they would not speak in their own defense. Most painfully, I watched my mother die from cancer. When she began to finally complain, it was too late. I am sure that she had symptoms long before she revealed it to us. She was the kind of person who would grin and bear it. She was so giving that she didn’t ever want to feel like she was imposing on anyone. I believe that her silence allowed the cancer to take [her] life because it was about one month from her diagnosis until her death.
In addition, what I learned from her is that our words make a lasting impression on this earth. Her words still live in me and the values she instilled in me live in me and will live on through my son.

Just like Susan Boyle, Lashunda has a special place in my heart. She's my inspiration!
