This would only require the investment of your time. Start with a blog on something you love. It could be anything. From a travel blog containing pictures of your travels to a sports blog dedicated to your favorite team/sport. You can blog about anything and everything. It doesn't matter. But write regularly! I've read that an online magazine editor would personally prefer someone who posts something daily over someone who writes long posts once or twice a week.
That’s a nice read! I love your many tangible ways mentioned to make passive income unlike certain people trying to recruit others by mentioning network marketing and trying to get them to join up and sell products like Amway, Avon, Mary Kay, Cutco or 5Linx. People get sucked into wealth and profits and become influenced joiners from the use pressure tactics.
Although adding income streams takes time, creating them within your current business is faster and easier than starting completely new income streams from scratch. This method of generating extra sources of income works well for any size business in any industry. For example, started by selling books. Today it sells thousands of other products including its own product, the Kindle, is a print and digital publisher, and now produces television shows. Many service-based business owners add coaching and books to their income streams.

1) If your property is not under rent control, you have the ability to raise rent to market prices with proper warning. In SF, I have to give tenants a one month warning for up to a 10% increase and a two month warning for up to 60%. Rent control limits to an inflation index, usually around 2% a year, which is why initial pricing and tenant turnover is important for better profitability.

Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.

Ask yourself how many hours a week do you spend sitting in silence, coming up with an idea and working on your idea? We’re so busy with our jobs that our childhood creativity sadly vanishes at some point in our lives. There are food bloggers who clear over $15,000 a month. There are lifestyle bloggers who make over $10,000 a month while living in Thailand. And there are even personal finance bloggers who’ve sold their sites for multi-millions.

Amazing that you saved between 50% to 75% living in NYC…I think that is one thing holding me back…the cost of living here. I’d like to invest in real estate, but I can barely afford to buy a place to live. I don’t need a large income to be happy, but I probably do need an income to support living in NYC as we don’t plan on leaving. The only thing I’m doing at the moment is saving in my 401K, IRA and a I dabble in stocks and P2P lending.
Everything passive first takes active energy. The time to put in the effort is when we are young and not ravaged by disease or burdened by family obligations. I remember being able to snowboard from 9am until 4pm every day for a year. Now, I’m lucky to last from 11am until 2pm without wanting to go to the hot tub and drink a bucket full of beer! If we can appreciate how lucky we are when we are young, we’ll be able to maximize our vitality and live financially freer when we are older.
I read about early withdrawal penalties on IRAs/401Ks very often. Almost always with a statement of “locked up” or “can’t touch” until 59.5. I’m sure you and well informed readers as well know about SEPPs in regard to IRAs/401Ks. For those that don’t SEPPs aren’t perfect but they are a way to tap retirement funds penalty free and I will be using in the future as I have over half of my equity investments within retirement accounts. South of a mil, North of a half. Let me add that I think your blog is outstanding.
However, under certain circumstances, payment for personal services performed in the United States is not considered income from sources within the United States.

Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
