There is a growing number of people who have discovered an easy way to make additional income. They have great software that has a number of affiliate programs already built in. Not only can you make money through Hubpages own earnings program (which pays through Paypal) but you can also get paid from Google Adsense, Amazon, Ebay and other programs.
According to the website, Craigslist makes money by charging a $10 fee for brokered apartment listings in New York City, $75 for job listings in San Francisco and charges $25 for job postings in six of its largest U.S. markets.
Say, if you want to rent your house (surely, not in New York) or sell your car, in the past, you had to buy classified space in leading newspapers, but today, you can post it for free and that too, covering a wider audience compared to newspapers.
Either you won't make good bets (betting on your favorite team even if they're on a horrible losing streak), and that you'll keep on playing after meeting the wager requirements, or you'll try other sports.
However, there are LOADS of other ways to write as you travel and make money, including blogging, picking up projects from sites like Elance and Guru, and writing travel guides, both online and offline.
