Jenny's mother, grandmother, and great grandmother literally mopped floors to give her the education, support, and encouragement she needed so that she did not have to. Dr. Laster figuratively mopped floors for her daughter, grandson, and countless others. She now asks, who mopped floors for you? And more importantly, who are you mopping floors for? Her deepest belief is that we all have a responsibility to pave the way for those who follow us. This is not just the story of her accomplishments, but a workbook for you, the reader, to document and celebrate your own achievements.
