Mark Gredler




Mark Gredler is an electronics engineer who worked for the Federal Aviation Administration (FAA) for more than thirty-three years, ten of those in a Civil Aviation Assistance Group in Madrid, Spain, where he helped improve the Spanish Air Traffic Control System. While living in Spain in the 1980s, when it was legal to use metal detectors to hunt treasure, Mark took up treasure hunting with his oldest son. At the age of five, that son found his first ancient coin, dated 150 BC. In the 1980s, Mark started making notes and outlines for a future novel based on his experiences in Spain. But it was a long, thirty-year process to produce and publish his novel, the first of a trilogy about an American living in Spain. He started the formal outlining and structuring of the novel after retiring from the FAA. Mark had to overcome discouragement from haters and fear of failure to get his novel down on paper. Key to accomplishing this was first taking action and then overcoming the barriers to successful persistence. Mark’s chapter in this book is a look at these barriers and how to overcome them to become successful. His goal in sharing this is to be “that somebody” that helps somebody else. Mark has published articles for the Celator magazine and contributed to the book, Juan Ruiz, Arcipreste de Hita, y el Libro de Buen Amor, Congreso 2017. He presented his paper in Spanish at this conference, and it was published in that book and in the online Cervantes Virtual Library. The paper is also available in English on his website with its English title, “Similarities Between the Libro de Buen Amor (The Book of Good Love) and Sexual Iconography in Romanesque Churches.”
