Since I first read his 38 at 12, they have lived in my heart. 39 ,I knew that my dad’s believing in me gave me permission to believe in 40 . “You will do something great.” He didn’t know 41 that would mean, but whenever I felt 42 of myself, I remember my father’s words, and 43  he were here, so I could ask, “Is this what you were 44 about, Dad?”
Many years have passed, and I believe that my father 45 have been proud when I 46 from basic training and became a rescue swimmer. Lately, I’ve come to realize he’d want me to move 47 to what comes next: to be proud of, and believe in someone else.

Trust me, love will be 54 real and their belief in themselves will be greater if you write the words on their hearts: “ 55 ! You will do something great.” Not having that blessing from someone they love may be the only thing holding them back.
