No matter how wealthy you are, I bet you'd probably appreciate having some extra money, right? You could use it to support a hobby, bulk up your savings, save up for a vacation, or just have in case of an emergency. But if you're already working full-time, you might think you're at capacity for how much money you can bring into your home. Not so, my friend!
In fact, there are all kinds of things you can do to earn a little extra money on the side. You could get an additional part-time job, although those can sometimes be even more stressful than your main job. You can also work for companies like Uber, Lyft, Instacart, or Postmates if you want to set your own hours.
However, those aren't your only options. There are a bunch of other options for making money that doesn't necessarily involve you working for another company.
