Great list! I have another to consider that I personally have 35+ years experience providing. Clean up litter outside commercial properties on foot using inexpensive hand tools. It’s almost as easy to do as going for a walk! I started doing this as a side gig in 1981 and soon grew it into a profitable full-time business. I share my experience in my book, Cleanlots.
Blogging is something that requires patience, persistence and discipline. It may mean writing everyday for over a year before you really start to see any money from it. There are exceptions to the rule, but from my dealings with other bloggers, it seems to be pretty common to spend one or even two years building your blog, your brand and your authority, before making any serious amount of money.
High-ticket consulting or coaching: You could sell your own high-ticket consulting or coaching products from your website. You'll still need a website, merchant account, sales funnel, lead magnet and many other items.

For every 10,000 points, you earn $10 with no limit on your earnings.

A person can stop living paycheck to paycheck, they can pay off their debt, and more all by earning extra money and learning how to make extra money.

I see a comment made by Stella including some freelance sites. This does work. I use oDesk and it’s been a big help in bringing in a little extra money. I also agree with some of the other comments that mention people should think of or view more ideas of making extra money, because it really is possible to make extra money instead of just sitting around moping about not having money to pay the bills or buy something special.

Let’s be honest. Those little people grow out of their clothes faster than you can keep up. When it’s time to get rid of the clothes they’ve outgrown, you have a few options.

And of course, you can use other sites like Poshmark, thredUp, Craigslist and eBay to sell children’s clothing too.
