I firmly believe in the powerful message of Ecclesiastes 3:1, which states that every endeavor man can undertake has its own time and meaning. Looking back on my own life, I see these different seasons as stages of growth that have helped me to understand my own potential and the path that I wish to take in life. I feel that I have lived deeply and fully, and now wish to apply the valuable life lessons I have gained to what I feel is my true calling. Now is the season to explore the fascinating world of medicine, and to finally make that dream a reality.
As a child, I never believed that I could succeed. Growing up in one foster home after another, I lacked the stability that a youth needs in order to excel in classes and build a proper foundation for the future. I was pregnant by the age of eighteen, and dropped out of school to try to forge a future for my children. Life was difficult but fulfilling, and I found much joy in being the mother of two lovely children. The day my second child was diagnosed with Krabbe’s disease, however, all of my happiness seemed to vanish before my very eyes.
