"Those whom God has chosen to be kings and to be at the head of the destiny of a country do not have any other choice than to start to understand the importance and the special characteristics of the position, because one can say that they start to become adults long before other boys of their age. If in this life it is as important to form and strengthen character enough to permit us to lead, it is not any less to know how to obey. In spite of the high positions that we hold in life, it will always be vital to know we also have duties to perform and obedience always involves real honor [...] We have to build a closely united family, without fissures or contradictions, we must not forget that on all and on each one of us are fixed the eyes of Spaniards whom we should serve with body and soul. I do not want to prolong my first letter any more in order not to tire you, but I would hope that this as well as the succeeding ones I send you leave a profound impression on you and are read calmly and thought about seriously."
-HM King Juan Carlos I to Prince Felipe of the Asturias, 1984
