Some of my list may be corny, but truly believe you can learn from anyone
1. Michael Jordan/Kobe Bryant/Tiger Woods/Few Other Athletes
Growing up I always wanted to be an athlete. Micheal Jordan specifically was such an inspiration. A real life hero. A Greek God.
Before social media, you didn't really hear about the negative side of people and Michael Jordan had a stellar reputation. He won at everything and was also known as the hardest worker around.
In today's era, when an athlete isn't winning they change teams. Michael Jordan (at least us older folks want to believe....) would never have done that. He'd get to work and figure out how to win. To be the best. At all costs. The Lakers/Celtics/Pistons used to dominate Jordan's Bulls and then he took over, with the help of the also great Scottie Pippen. The Robin to Jordan's Batman.
Recently, watching Jordan's documentary on Netflix you saw a different side of him. He was a killer. And he also had some sadness in him. No one is perfect. Look up to others, but don't assume they are perfect and put them on pedestals.
Kobe Bryant, after Jordan, was the next athlete I loved to watch compete. He wasn't a perfect person, but gave inspiration in his work-ethic, talent, and demeanor. He passed too soon and seemed to be ready to do great things after his playing career ended.
Tiger too is an imperfect human. Recently, hes overcome a terrible car crash and is competing again.
These athletes have given many people joy and inspired millions by their craft and brilliance.
