I personally haven’t tried any of the below methods so I can't speak from experience to how they work. In my mind, the most lucrative way is through building a REAL business online and providing your visitors with great value. However, after some thought, I decided to include these here because, quite often, the biggest roadblock for many is a mental one: believing that making money online is possible. From my experience, once you have made your first dollar, or even your first cent online, the world is suddenly a different color.

I see you include rental income, e-book sales and P2P loans as part of your passive income. Do you not consider your other internet income as passive? Is that why it’s not in the chart? Or did you not include it because you would rather not reveal it at this point? (I apologize if this question was already answered – I didn’t read through all the comments, and it’s been about a week since I actually read this post via Feedly on my phone)

Whether you take a “distribution” (aka free-cash-flow) in the form of a dividend, interest payment, capital gain, maturing ladder of a CD, etc, you are still taking the same amount of cash out of your portfolio. Don’t fall for the trap of sub optimizing your overall portfolio’s performance because your chasing some unimportant trait called “income”.
Creating passive income is the key to retiring, especially retiring early. If you want to retire early with the stock market you will have to save a huge amount of money, because that money has to last so long and retirement calculators depend on you using your investment to fund your life. With passive income you will have income coming in as long as you own the investment, without every eating away at the principle invested. Creating passive income may take more work than investing in the stock market, but I think it is well worth the extra effort!
