When you're at the very start of your life/career, there are very few jobs that have absolutely zero runway to somewhere/thing else. Even if you're waitressing in a cafe, by doing a bit extra like cashing up, helping with restocking etc etc you demonstrate an attitude/ develop skills that could either lead to you being offered more, or when you go to interviews for your better job prospect, you can talk with conviction about what else you did.
I now run my own business, earn very good money, and don't work 75% of the time. But I got here through working some very long hours ('overtime' in the form of a bonus ultimately worth 75p an hour I worked out one year) that gave me valuable experience and ultimately enabled me to do what I'm doing now.
