Today's companies don't want to just sell their products. They want to be top-of-mind with customers, generating goodwill and engagement. Many businesses do this by creating newsletters, emails, custom landing pages, social media posts and various other forms of content on their websites and apps across a variety of platforms (desktop, mobile, social, email, etc).
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
Now, making money online should seem like a pleasurable activity. Why wouldn't we do just about anything to see things through, since it would be a major source of pleasure, right? Wrong. In the beginning, like anything else, we might get really excited about it. We might also set our hopes very high. But that all comes crashing down when we begin to fail.
