One idea could be to get your dad a book on public speaking or leadership. "Talk Like TED" by Carmine Gallo and "The Charisma Myth" by Olivia Fox Cabane are both great options. Additionally, you could sign him up for a public speaking or leadership workshop, or find a local toastmasters club for him to join, providing the opportunity to improve his public speaking skills further. Finally, you could create a personalized gift basket filled with items he might need before speaking such as his favorite snacks, water bottles, a new notebook, and pens.
Or you can get him a star map with the date when he welcomed you in this world.
