Agreed but I might consider a blended portfolio of large and small cap stocks using low cost mutual funds (I found a fidelity large cap fund FUSVX with a net expense of .035% that has also delivered 17%+ YTD gains, some are dividend some are growth stock in the fund) UNLESS you’re close to retirement. This way you get the growth upside on small cap paired with the stablilty of some large cap stocks while maintaining balanced ricks.
Renting value is exactly what you do when you go to work every day. This is a great way to adhere to our rule against one-time consumption, although you can only rent something to one person at a time (drawback). By renting something, I can generally avoid degradation of the value, or at least lessen it. By renting you a house, I’m charging you for the value of the shelter and comfort, and in fact incur pretty minimal decrease in value as your usage of the house causes wear and tear. When you’re done renting the house, there’s still plenty of value left to rent out, and the fact that you’ve enjoyed a year or two of value doesn’t much matter to the next willing consumer.
Investing in rental properties: Another form of real estate investment, rental investments (i.e. becoming a landlord) could steer you down the passive income path of steady monthly rent checks that you can use to pay off a mortgage loan on the rental property. After the mortgage is paid off, those monthly checks go right into your bank account -- potentially for years to come. 
Hey Alison! thanks for taking the time to check out the post! I specifically outlined the post so it would follow a specific structure. This is so readers know what to expect and it helps with the flow of the piece. I’ve actually just finished up a (shortened) PDF version of the post that includes a bonus idea not mentioned here. I’ll be adding this to the post shortly! You’re right on the ebook suggestion — could easily have been made into one. I noticed that you linked to it from the millionaire blog post, thank you so much. Kimberly and I really appreciate the mention.
“I don’t believe the overnight success exists. There’s a lot of hard work and time involved beforehand,” say Flynn. Angry Birds may have seemed like an overnight success but it was the 52nd game that Rovio created. Flynn says it took him a year or year and a half to build audiences for his most successful sites.

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!
