In my experience, it’s product-related blogs that tend to do best with Amazon. Most blogs probably have at least some possibilities (for example here on ProBlogger I occasionally link to a book that relates or a computer or electronic tool that I think might be useful to bloggers) but the reality is that this blog will never convert as well on Amazon as my photography site.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
House sit if you have neighbors who go on vacation. Water their plants, take out the trash, check the mail, and keep an eye on things. They may ask you to visit 1 to 2 times a day or even spend the night at their house so it doesn’t look empty and prevents burglary. Follow all of your neighbor’s rules and instructions and always lock up the house when you leave to keep it safe.
Get-rich-quick schemes and fad weight-loss diets are naturally popular because they satisfy the id while also attending to the super-ego. The ego's job is complete when it sees something like this. The appeal of "fast'' stems from the innate desire for instant gratification, so beware of what seems too good to be true (they often are) when you're looking to make money quickly. Be wary. Listen to the conversation deep within the confines of your mind and do your best to tame the proverbial beasts.
Throw a bake sale if you like to cook. Choose classic recipes that are easy to make in big batches like chewy chocolate chip cookies, fudgy brownies, or vanilla cupcakes. Once you bake everything, separate your goodies into individual servings and place them in pretty packages like treat bags tied with ribbons. Set up a stand in your front yard or out on the street corner to get more traffic.
