My mom was dying for me to write a book, she was my biggest advocate.

Cruz frames authorship as an act of filial devotion and gratitude: the impulse to write is tied less to personal branding than to honoring a parent’s faith in him. The line also underscores how creative projects can be sustained by intimate, behind-the-scenes encouragement—“biggest advocate” suggests emotional and moral support that precedes public recognition. Read alongside Cruz’s public persona as an athlete, the quote highlights a shift from physical performance to narrative self-definition, implying that telling one’s story can be a way to preserve family legacy and repay belief with a tangible, lasting work.
