Use the law of supply and demand to your advantage. Most of us are familiar with the law of supply and demand--the more there is of something, the cheaper it is; conversely, the rarer the product or service, the more expensive it is. However, other than when we get to a toy store before sunrise to get on line for the latest fad toy that kids can't get enough of, we don't really apply the law of supply and demand to our own lives--particularly our careers. For example, if you're aspiring to do something that many, many other people want to do (so much so that they do it for free, as a hobby) then it will be far more challenging for you to make money doing it. On the other hand, if you do something that most people don't want to do, or if you get very good at doing something most people don't do all that well, then you can make a whole lot more money. In other words, choose a career in pharmacy over photography.
Evaluate Web sites. Another way to make extra cash in a short amount time – $10 for about 20 minutes of work – is to sign on with UserTesting and evaluate Web sites. You need a computer with a microphone and Internet connection, and you’ll have to fill out a one-page demographic profile. You’ll receive work if your profile matches that of the target audience of sites being tested. Then it’s just a matter of using UserTesting’s screen recorder, which you'll need to download to your computer, to record your verbal comments and on-screen movements as you click through a site. Site owners typically are looking for feedback about whether the Web site is confusing to navigate.
The ego is the driver making the decisions. It decides between the devil (the id) and the angel (the super-ego) on either shoulder (yes, all those cartoons you've ever seen are partly true). We have voices in our mind, and it's up to the ego to decide which one to fulfill. Its goal is to satisfy the id in some way while also attending to the super-ego.
Become a mystery shopper. This means doing business with various establishments and rating their products and services without their knowledge. It may sound like cake, but remember that it requires discreteness, a good memory for detail (ex. the name of every individual who helped or served you), and enough cash for you to be able to pay for your shopping experience up-front and then wait to be reimbursed pending the approval of your review.
