Steve Jobs
Steve Jobs famously dropped out of college to start Apple, partly because his parents struggled to afford his education, and he didn't see value in the classes.
During this time, he slept on friends' dorm room floors, returned Coke bottles for food money, and walked seven miles every Sunday to get a free meal at the Hare Krishna temple. This period of hardship shaped Jobs' resourcefulness and determination, which later fueled his success.
