In These Four Wheels, Xavier shares insights into his life's journey. He has faced obstacles that would have stopped many others in their tracks, but through his determination and perseverance he has prevailed. He vividly and candidly explains the acts of discrimination and inequality that he and many others with limitations and disabilities encounter on a regular basis. Some of the chapters shared are The Differences, The Facts of Life, Through it All, and How Could I Change the World. You will realize that we all are not that different and many limitations we experience are self-imposed.
