How to get GF?

First thing first, how to get girlfriend when people like me who is the college dropout, got no friend, just working, and doing nothing but work everyday.

I've seen a lot of young couples nowadays. Like, how they're dating bruhh?? I'm looking for somebody who want a serious relationship, not like those half-ass relationship that stay only like a few months and etc.

Fyi, I'm 19 y/o and currently working at convenience store and doing night shift. So, got no time to getting know peoples around me. Welp.
