I am very fond of having multiple sources of income. The blog is my second source and dividends are my third source of income. I have friends who have a second job and other passive income sources. Here are some ways they earn passive income. But forget looking for a real estate property, applying for a loan and then finding a tenant, you can earn some side money from internet-based jobs. They range from purely technical ones like, create an application, designing web pages to something very trivial like answering a survey, participating in giveaways.
Blogging on a self-hosted domain, to earn money on the side, is still the best way in 2015. This year my blog income went up to $6,000 in April, an all-time high. I started with a $70 income at my 7th month, back in 2011. The more content you publish, it attracts more visitors. Want to open a blog of your own? I have this easy to follow guide to start your blog in 20 minutes and $20.
