Thanks for asking. gives a good summary of the definition I use. But in brief, it’s income that isn’t proportional to the time you physically put into acquiring it. It doesn’t mean it’s not without work or effort. It’s just that most of the work is done up front and it continues to pay off long after that initial effort. Real estate fits into that box. There’s definitely a spectrum but compared to what we do as doctors, where our compensation is directly linked to our time, most of these things are quite passive.
Use your base to build your audience, and when you’re starting out, take advantage of the fact that you don’t have a big following to give more personalized help to your first fans. “The people who are starting out — that’s their advantage,” says Flynn. “They have the opportunity to speak directly with those people few coming their way to find out what their problems are and give them the special treatment that bigger brands might not be able to do.”
“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.

​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!
If there’s one thing I’ve realized, it’s that I’m not alone. There are so many physicians who are not at an optimal place with their jobs and are unhappy with medicine in general. Physician burnout is a hot topic these days. According to the experts, a good deal of that comes from the loss of physician autonomy and relationship with the patient, but I believe a good amount of it also comes from the increasing financial pressures heaped on physicians (decreasing reimbursements, rising student loan debt, increased standard of living, and more).

Bullshit. If you have a job, you have marketable value. Maybe it’s low value, if you’re flipping burgers, but you can create value somehow. I don’t care if you have to start out by re-renting the parking spot in front of your apartment, you can find, create, or buy something valuable worth repeatedly selling or renting, or you’re not thinking hard enough. Here’s a free idea: A lot of people want to play with 3D printers. Get 5 of your friends together and buy one. Put up a website and a listing in the local paper. Charge $50/h for printing. Set up a system that verifies if payment has been submitted and then automatically prints out the files that have been emailed to you. Split the earnings with your friends. Boom. You have passive income.

Lending Club is a platform where you can lend your money to other people. You’re the bank. Each note is only $25, so you can invest $1,000 and lend money to 40 people. There are many grades of loan (from safest to riskiest) and investors earn, on average, between 5% and 7% annualized returns. For more information, check out Investing and Making Money with Lending Club Peer-to-Peer Lending and my real money Lending Club Portfolio.

2. Focus on income-producing assets. Internet growth stocks may be sexy, but they provide no income. To build a large enough passive-income stream to survive, you must invest in dividend-generating stocks, certificates of deposit, municipal bonds, government Treasury bonds, corporate bonds, and real estate. You're free to invest in non-income-producing assets for capital appreciation too. You just want to earn reliable income when the day comes to leave your job.
That strategy seems waaaayyyy less risky than actively picking stocks of supposedly “reliable” stocks that issue dividends, which could be cut at any time due to shifting industry trends and company performance. Dividend investing feels like an overly complex old-school way of investing that doesn’t have a very strong intellectual basis compared to index investing.
So, armed with my real estate license and this desire to help physicians (and create a business at the same time), I started a real estate company called Curbside Real Estate. My goal was to help physicians buy and sell homes by connecting them to trusted realtors and lenders. It started organically, largely through word of mouth. Next thing you know, I was helping doctors from coast to coast. The business was great and I felt I was making an impact helping physicians, but I still wanted to own my own real estate investment properties.

If you know anything well, a place, how to fix something, how to make something, how to do something, you can write a guide for it. You can sell your guide as an e-book, offer it as a download for a fee on your site or reach out to bloggers with similar content and ask if they will offer it as a paid download on their website (for a price of course).

My favorite type of semi-passive income was rental property because it was a tangible asset that provided reliable income. As I grew older, my interest in rental property waned because I no longer had the patience and time to deal with maintenance issues and tenants. Online real estate became more attractive, along with tax-free municipal-bond income once rates started to rise.
If you’ve ever thought to yourself, “I wish there was a product that did this,” then invent it! Create a product, medical or otherwise, and sell it as a company or get royalties for it. It’s not impossible to figure out, I have many friends who have taken a concept to market. Don’t overlook an invention as a fantastic means of attaining passive income.
