Roy Clay has written a masterpiece that is captivating from its action-packed introduction to its soul stirring ending. His inspirational words re-count a near century long journey that captures his unlikely rise from humble Midwest beginnings to an American technology pioneer and Silicon Valley entrepreneur. I highly recommend this accurate account of how his unrelenting vision and determination helped pave the way for me and many executives who came behind him. Thanks Roy, for opening doors, and thumbs up for this brilliant memoir that is a must read for all. John W. Thompson, Chairman of the Board, Illumina (former Chairman of the Board, Microsoft)

I first met Roy in 2000 and he instantly embraced the Rainbow PUSH Coalition's campaign for equity, diversity and inclusion in Silicon Valley and the tech industry. He talked to me about his personal experience, where his peers in several companies rose to the highest heights while he was stifled. There was no talent deficit, but an opportunity deficit. But Roy proved as he has all of his life - battling segregation in St. Louis to breaking down walls of exclusion in Silicon Valley - that he would be unstoppable. Roy's exhilarating story is a model for all to keep hope alive and never give up on your fight for dignity and respect. Roy's book is a must read and a guide for all those striving for excellence and equality. Reverend Jesse L. Jackson, President and Founder, Rainbow PUSH Coalition. American civil rights leader and activist
