This book by Father Carlos Miguel Buela (IVE) is directed towards those young people who are the main protagonists and builders of the third millennium. Living in the 21st century is considered both a great gift and a difficult challenge. In these pages, Father Buela writes why being a youth in the third millennium is such an adventure. Amidst the uncertainties and difficulties plaguing young minds, Father Buela encourages youth-equipped with the truths and pillars of the Catholic faith-to live great ideals and experience the beauty and joy of God in the present world. In the midst of turbulent seas, a Captain cries: Duc in Altum! Go into deep waters! Few know what this phrase really means. Those who have been able to understand it know what the secret to true, authentic happiness is: eternity.
