"There are people who appear in the magazines and I don't know who they are. I've never seen anything they've done and their careers are over already. They're famous for maybe 10 minutes. Real careers, I think, take a long time to unfold"

In this quote, Matt Damon is revealing his thoughts on the fleeting nature of fame and the superficiality of the show business. He acknowledges that there are individuals who are constantly featured in magazines and touted as stars, however he personally does not acknowledge them or their work. He thinks that their fame is short-term, lasting only about 10 minutes, which true success and longevity in a profession requires time to develop. Damon is highlighting the significance of effort, dedication, and determination in constructing a meaningful and enduring profession, rather than looking for instant popularity and recognition.
