You can also participate in focus groups. Focus groups are hired to test products and give opinions before they reach the market. You would be a critical component of verifying they will have success and reach a high return on their investment. Surveys and focus groups are not ‘get rich quick’ schemes at all, but you can generate a few hundred a month.
Think about it.  If you are saving for retirement, you are trying to save enough in investing to generate enough income to replace your primary salary.  Let’s take my friend’s example above: $50,000 a year.  To generate $50,000, you would need to have almost $1,700,000 saved, and be able to generate a 3% cash flow on that money (which is reasonable if invested in dividend paying stocks).
Brian had found a huge need for web design in the restaurant and food truck space. After getting tired of working with client after client, he decided to turn his service-based business into a product-based one. He made his services more standardized and productized. He eliminated all his client work and created templates and products to serve that market instead. And it’s been going great for him.
When withdrawing money to live on, I don’t care how many stock shares I own or what the dividends are – I care about how much MONEY I’m able to safely withdraw from my total portfolio without running out before I die. A lot of academics have analyzed total market returns based on indices and done Monte Carlo simulations of portfolios with various asset allocations, and have come up with percentages that you can have reasonable statistical confidence of being safe.
I've now only got an SF rental condo and a Lake Tahoe vacation rental in my real-estate-rental portfolio. Although I miss my old house, I certainly don't miss paying $23,000 a year in property taxes and another mortgage, and dealing with leaks and managing terrible tenants. I drove by the other day and couldn't believe how much noisier and busier the street was than where I currently live. I wouldn't be comfortable raising my son there.
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)
Indian economic policy after independence was influenced by the colonial experience, which was seen as exploitative by Indian leaders exposed to British social democracy and the planned economy of the Soviet Union.[110] Domestic policy tended towards protectionism, with a strong emphasis on import substitution industrialisation, economic interventionism, a large government-run public sector, business regulation, and central planning,[118] while trade and foreign investment policies were relatively liberal.[119] Five-Year Plans of India resembled central planning in the Soviet Union. Steel, mining, machine tools, telecommunications, insurance, and power plants, among other industries, were effectively nationalised in the mid-1950s.[120]
India is one of the largest centres for polishing diamonds and gems and manufacturing jewellery; it is also one of the two largest consumers of gold.[183][184] After crude oil and petroleum products, the export and import of gold, precious metals, precious stones, gems and jewellery accounts for the largest portion of India's global trade. The industry contributes about 7% of India's GDP, employs millions, and is a major source of its foreign-exchange earnings.[185] The gems and jewellery industry, in 2013, created ₹251,000 crore (US$35 billion) in economic output on value-added basis. It is growing sector of Indian economy, and A.T. Kearney projects it to grow to ₹500,000 crore (US$70 billion) by 2018.[186]
​Self Publishing is mainstream today. When you purchase an eBook off of Amazon there’s a pretty good chance you’re buying a self-published book. Self-publishing is also ridiculously easy. I tried this a few years ago and couldn’t believe how simple the process was. To self-publish a book you’ll first need to write and edit it, create a cover, and then upload to a program such as Amazon’s Kindle Direct Publishing. Don’t expect instant success though. There will need to be a lot of upfront marketing before you can turn this into a passive income stream.
In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
