Sinval is a passionate reader of leadership and influence stories, exploring the trajectories of political, religious, and visionary figures who shaped the world. Married and a proud father of three children, he balances his family life with the entrepreneurial spirit that led him to open a laundry to wash the linens of the restaurant he manages. An admirer of the UFC and the discipline behind martial arts, he values both strategy and strength — inside and outside the rings. When he is not immersed in books or behind the scenes of his business, Sinval prefers the tranquility of home, where he finds inspiration to write and reflect. His writing seeks to provoke, inspire, and connect readers with ideas that transcend borders.
