Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online. 
Some scams might involve asking you to pay for a “training” book or CD that explains how to make money in a certain business. Others charge for supposedly “exclusive” products that you’re supposed to sell at a premium. Avoid both of these scenarios. Remember, you should never have to pay to get a job. And if someone asks you to, you can be sure that it’s a scam.
Just ONE of the training courses on my site typically sells for up to $47 – and there are currently more than 200 internet marketing video training courses included in your membership. That doesn't even include all the articles, guides and audio courses I'm offering! The cost of a membership is about 1% of what it would cost for you to buy all of these training materials individually. Don't delay – buy today!

Looking for keyword opportunities involves strategically looking for a product or niche online based the keywords people are search for in search engines like Google and Bing, then identifying high volume but low competition search terms. Keyword research can be a bit technical, so this opportunity involves a solid base understanding of keyword research and search engine optimization (SEO).
Persistence and Commitment. You’ll need to have a good amount of persistence while pursuing freelance writing gigs. This business is subjective, and while one person may love your writing, another may not. Do your best to always produce good, solid copy and hold on to your commitment to do the best you can for your clients. Just by committing to do those two things, you’ll be miles ahead of your competition.
Location. The most successful bed and breakfasts are those that are convenient to airports, historic parts of town, or other tourist attractions. That’s because there are two types of guests who tend to frequent B&B’s: business travelers who are tired of sterile hotel rooms, and families looking for a unique experience. That’s not to say that you can’t develop a successful B&B if your home isn’t located in the perfect spot, but you might have to work harder to make it a success if it isn’t.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!

This is when they’ll tell other potential buyers whether the book was in the condition that you described, whether it was mailed on time, and if your communications were pleasant and helpful. One bad rating can hamper sales, and a couple of them can downright stop them. Excel at customer service and your ratings will help your company grow.
