Once that comes to mind for me is this guy
That’s not Starlord, it’s the actor who plays him, Chris Pratt. Chris happened to wrestle in high school, and he wasn’t half-bad considering he placed 5th in a state tournament in Washington. His coach asked him what his goals were after high school, to which Chris responded, “‘I don’t know, but I know I’ll be famous and I know I’ll make a shit ton of money.’ He elaborated in a later interview, “I had no idea how. I’d done nothing proactive.”
-Pratt dropped out of community college halfway through the first semester and, after working as a discount ticket salesman and daytime stripper, he ended up homeless in Maui, Hawaii, sleeping in a van and a tent on the beach. He told The Independent, “It’s a pretty awesome place to be homeless. We just drank and smoked weed and worked minimal hours, just enough to cover gas, food, and fishing supplies.”
At 19 years old, Pratt was waiting tables at the Bubba Gump Shrimp Company restaurant in Maui when he was discovered by actress and director Rae Dawn Chong. She cast him in her directorial debut, the short horror film Cursed Part 3, which was filmed in LA.-

He kept picking up parts, notably in the hit sitcom, Parks and Recreation, to supporting roles in feature films.
And the rest is history…
