Can you earn a decent income online?

Yes, definitely. Realistically speaking, a high five-figure annual income is definitely an attainable goal for an individual working full-time from home. In case you have a day job, it will take somewhat longer to generate a livable income. However, it can still be done part-time – you just need to be willing to devote most of your spare time to it. Once you get the basics worked out, it becomes pretty much self-sustaining, and then you don’t need to devote so much time to it as much of the hard work has already been accomplished.
