There are a couple of problems with direct investment in real estate though.

One of the simplest ways to enjoy passive income streams is to buy stock in healthy and growing companies that pay dividends. Better still, look for dividends that have been increased regularly at a good clip (many companies often hike their payouts annually) and that have room for further growth, as evidenced by a dividend payout ratio of around 70% or less. The payout ratio is the amount of the annual dividend divided by the trailing 12 months' earnings per share. It reflects the portion of earnings being paid out in dividends. The lower the ratio, the more room for growth. A ratio above 100% means the company is paying out more than it earns, which isn't too sustainable.

The secret to this example of viral marketing (which has clocked up over millions views both online and offline) is very simple: a product so great that it turns people into fans of the brand all on its own. People love themselves. If they have the possibility of spreading this love digitally through selfies, it’s almost a guaranteed win. The iPhone X’s brilliant selfie feature spread virally through various media forms before apple repurposed the viral content into one masterpiece, the iPhone X selfies film. As one of the YouTube comments says, “It’s the most beautiful thing I’ve ever seen”… This viral marketing through video has allowed Apple to spread key features such as their Portrait Lighting effects and their TrueDepth camera.
