Making money is as critical as saving it, and if you're a stay at home parent or between jobs or disabled or in any other position where you need to make money, working online is the ideal way to bring in an income.
There are still scams and "methods" all over the internet, so beware of them. They are usually overly enthused about how much you can make or how little it takes to get rich, but some of them have become a little more sophisticated. It's best to do some research on any company or site before getting involved with them.
You can make a few dollars here and there or, if you're really committed, you can make more than just a few. Honestly, unless you have a specific skill or are an entrepreneur at heart, it's very hard to make a living online. At best, most people will make enough to pay for their internet and maybe pay a bill or two each month.
For some, that's fine. It's perfect, as a matter of fact, for some people. There are several sites where you can work to do that: the ubiquitous Swagbucks is probably the most popular. It takes time, as do most rewards type of online programs.
Then there is Inboxdollars and InstaGC and many more. Once you start looking, you will find many and you'll have to choose wisely if you want to make the most of your time.
"Pocket change" means different things to different people, so you may or may not be happy with what you can earn at places like those.
From a little experience, I can advise you to stay with a site for at least a couple of weeks until you learn the ropes. They're all a little different and you will find new and better ways to earn as you get more comfortable with each of them.
And have fun. It's not all about work and money. Set goals, challenge yourself, enjoy your time and know that you're not wasting it.
