The value of hard work - Advice for young people | Don Lincoln and Lex Fridman

Don Lincoln opens by describing his humble origins — growing up poor in a rural area with supportive but academically limited parents. His mother could only help him with math through sixth or seventh grade, yet his environment was nurturing. Two major intellectual influences shaped his early path: a voracious appetite for science fiction (reading a book a day as a child), which fostered imagination, and popular science communicators of the 1970s such as Isaac Asimov, Carl Sagan, and George Gamow, who wrote accessible science books for lay audiences. These influences, combined with an irrepressible curiosity about deep philosophical and cosmological questions — such as the origin, nature, and fate of the universe — drove him toward science.

In college, Lincoln pursued minors in philosophy and religion hoping those disciplines might answer his deepest questions, but ultimately concluded that science was the better path. He then faced a fork between cosmology/astrophysics and particle physics. In the mid-1980s, cosmology had relatively few empirical measurements, while particle physics offered the ability to run actual experiments and get concrete answers. That empirical rigor drew him to particle physics.

Lincoln then discusses his legendary work ethic as a graduate student at Fermilab. Without family obligations, he voluntarily worked Monday through Saturday from 8:00 a.m. to midnight, and Sundays from 8:00 a.m. to 5:00 p.m., using the remaining Sunday hours for chores. He emphasizes that this was driven entirely by passion — he simply couldn't imagine doing anything else. He argues that while intelligence is necessary, the traits that truly distinguish great scientists are drive and grit. For him, a failing experiment didn't produce discouragement but rather anger and renewed determination to solve the problem.

Finally, Lincoln reflects on why he invests heavily in science communication — writing books and making videos. He grew up without access to the mentors and resources that children of educated families often have, and he wants to reach other kids in small towns across America who are in the same position he once was. He notes that he has already seen the tangible impact of this work, with summer interns at Fermilab telling him they were inspired by his content. He closes by suggesting that one of those young viewers might be the person who answers the big unanswered questions in physics.
