Working a regular job and still not making enough money to pay your rent, bills, and other expenses can be one of the most frustrating feelings in the world. Unfortunately, this is a situation that many people, especially those with only part-time or minimum wage jobs, find themselves in. Here are four creative ways you can make ends meet when your job just isn't bringing enough money in.

Drive for a Cab Company

If you have a newer car, good insurance and some time on your hands, driving for a cab company, such as Uber or Lyft, can actually make you some very appreciable money on the side. Though you won't get rich using your car to drive other people around, full-time Uber drivers can make $35,000 or more every year. If you just need a little money to supplement the income from your job every week, Uber and Lyft are easy ways to make it.

Get a Roommate

If you can't increase your income, how about decreasing your expenses? One of the easiest ways to lower the cost of anything is to split it with someone else. If you are single or living on your own, consider finding a roommate to split your rent and bills with. Though it may not be the most convenient arrangement in the world, it can drastically reduce your cost of living.

Apply With a Staffing Agency

Businesses are always looking for people to work with them. If your primary job isn't making you enough money, consider signing on for a temporary gig through a staffing agency. If you're working a part-time or minimum wage job and would like to enter a more profitable career, try an industrial staffing agency, such as Labor Works, that can get you experience in factory, construction and production work.

Sell Your Skills

If you have design, video, audio, writing or marketing skills, you may be able to turn them into a secondary income by becoming a freelancer. Freelance workers can use various platforms to find clients, work and get paid on their own time. While turning freelance work into a full-time income takes a great deal of time and effort, making a little extra money to pad out your existing income is substantially easier.

These are just a few of the many ways to make ends meet when the job you already have isn't quite doing it for you. If insufficient income is a regular part of your life, however, you should ultimately be looking to secure a different job.
