great information. i recently used your “Start an Online Store” suggestion, but quick turned it from junk in my garage to small business. i found a way to make some quick doe. i found these, “8 point and 7/16 wrench catv cable star key security tool” listed on eBay for $50.00 each. Found the source (newelectronx) that sells them for $5 to 15 bucks per piece. I sell them on craigslist for a good return. i’ve been making good money every since. i’m not wealthy yet, but income is going smoothly and sell aren’t that bad. profit is at least $35 per sale. if i sell eight pieces per day then i make like $280 which is better than a 8 hour job to me. so online selling works.. try it
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service and refunds. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. It is hard work, especially on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not. 
I know starting a blog is a way to make extra money.  I just wish it was not take so much time it is not easy. To come up with new things to write about plus getting the traffic to your site. Just like your list here no way you just set down and wrote this all at once it took a lot of research and searching your brain.  Great info and thanks for taking the time to put it all together.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.

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.
Secondly, I notice that your blog earns you some good money. I am surprised to know that you get over $100,000 per month. I also have a blog – http://www.golaserengraving.com/blog – which I want to monetize and I have tried Infolinks Ads and PropellerAds. What other better options can you advise me to venture into to make reasonable amount of money?
Amazon makes it fairly easy to list and sell old books, games and devices on its marketplace. You can make more than just a few bucks If you have pricey textbooks from college. Be sure the books are in good condition. You'll get negative reviews if you attempt to sell books that are falling apart or games that are scratched up. Remember, be upfront about any defects, no matter how small they might be and no matter how few people might readily notice it. 
If you hook up with a for-hire car parking service (the type hired out for fancy neighborhood parties) you can make some nice cash tips in just a few hours at night and on the weekend, when parties are held. The key here is to do a great job by showing hustle and being super friendly. This was one of the most enjoyable jobs I had during graduate school. Who doesn’t like to drive nice cars?

First off, I’m a blogger so it seems wrong not to mention it, but more importantly, it’s a legitimate way to make money. It’s quite possibly the least straight-forward way on this list, but it’s very doable and it’s also quite possibly the funnest way on this list. I love blogging and I know hundreds of bloggers who feel the same. So let’s talk about making money blogging and what it really means.
