William Hartwick, a retired first-grade teacher and former elementary/middle school principal, has spent his life transforming challenges into opportunities. Residing in St. Augustine, Florida, after a fulfilling career in education in Crescent City, California, he has become an award-winning author and motivational speaker, touching lives through his story and advocacy.
Living with Tourette Syndrome and Bipolar Disorder, William wasn’t diagnosed until the age of 35. These life-altering experiences inspired him to pen The Invisible Backpack: A Life of Courage, a deeply personal and moving narrative written entirely in rhyme. Despite being labeled functionally illiterate in his school years, William has harnessed the power of words to channel resilience, hope, and courage. His book serves as a beacon for anyone carrying the unseen burdens of life, encouraging them to embrace forgiveness, acceptance, and love to lighten their emotional load.

William’s expertise goes beyond storytelling. With an extensive background in education, he’s a champion of mental health, neurodiversity, and inclusive learning environments. His workshops and speaking engagements aim to empower students, educators, and families to shift perceptions, embrace diversity, and foster understanding for individuals navigating challenges like Tourette Syndrome and Bipolar Disorder. Through these efforts, he hopes to create a world where everyone feels seen, heard, and valued.
Not one to rest on past achievements, William has laid out a detailed 14-month plan to regain personal, professional, and financial independence. This ambitious roadmap includes launching merchandise like the TOTO Bag, expanding book sales, securing speaking engagements, and forming partnerships with progressive organizations. It’s a testament to his unwavering dedication to growth and his mission to inspire others.
William also emphasizes the importance of mental health, committing to self-care, professional support, and spirituality as cornerstones of his journey. He encourages everyone to wake up each day with a positive attitude and the willingness to embrace life’s challenges.
Through his writing, speaking, and relentless advocacy, William Hartwick continues to transform lives, proving that with courage and determination, one can rise above life’s hurdles.
