One great gift idea for your dad might be a self-improvement book that he hasn't read yet. Some popular options include "The 7 Habits of Highly Effective People" by Stephen Covey, "Mindset: The New Psychology of Success" by Carol Dweck, or "Atomic Habits" by James Clear. Alternatively, you could consider getting him a subscription to a self-improvement podcast, such as "The Tim Ferriss Show" or "Optimal Living Daily". If you want to get him something more hands-on, you could consider booking him a session with a life coach or personal trainer.
Or you can get him a star map with the date when he was born.
