For example, writing a book is a passive income stream. You write it once and sell it over and over. The word passive is a little deceptive because you need to market the book. Nevertheless, compared to non-passive sources of income, which you need to do over and over to make money, such as providing a service, passive income streams require less time once they’re created. Other forms of passive income include other written works (i.e., courses), audio or video creations, affiliate marketing, licensing your idea, franchising, or continuity programs (i.e., memberships).
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.
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.
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.
