Google AdSense. These pay-per-click ads appear on your blog. Every time somebody clicks on an ad (which is supposed to be about a subject related to your niche), you make a few cents. Small amounts each time, but it adds up. This is extremely hands-off. You just need to get a code from Google, place it on your website - and the ads will automatically appear on your blog. Google will only show ads that are relevant to your blog so it's a good experience for your visitors and maximizes the amount of clicks you get, meaning more income.
A friend in Boston made a living doing this. He had lived in the Netherlands and was fluent in Dutch. He contacted companies who sent people to the Netherlands to work and live, and offered to provide not just his language expertise but important information on Dutch culture and living in the country. It worked. If you’re from or have lived in another country, consider channeling not just your language but your cultural expertise into a new career.
As Paul and Sarah Edwards noted in their book Working from Home, successful home-based business owners are usually good at what they do and enjoy doing it. It is also helpful to be independent, self-sufficient, and flexible. Other keys to success include being able to sell oneself and the business, and staying on top of personal and business finances. Since it is often difficult to associate being at home with working, home-based business people must be able to maintain boundaries between their personal and professional lives. In addition, they require a great deal of self-discipline to overcome the sense of isolation, frequent distractions, and lack of motivation and concentration that commonly affect those working from home.
There’s more to being a coach or personal trainer than just being fit and loving to exercise. Finding a specialization is important, and licenses might be required for certain types of coaching roles. For instance, a friend in Boston obtained US and European soccer-coaching licenses before opening a successful one-on-one soccer-instruction business.
