I like my job but I wanna make more money

My paychecks are like $1000 every two weeks. That's like barely making it. I can afford rent and my car payment but I can't really save as much as I would like to. I've been thinking about going back to my old job which pays a decent amount more but I like the people I work with and stuff. I get along with my co workers and shit. I really do think they're cool people and the work load is very light. I don't feel stressed at work at all. It's just I need a bit.more.cash
