Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.
7) Never Withdraw From Your Financial Nut. The biggest downfall I see from people looking to build passive income is that they withdraw from their financial nut too soon. There’s somehow always an emergency which eats away at the positive effects of compounding returns. Make sure your money is invested and not just sitting in your savings account. The harder to access your money, the better. Make it your mission to always contribute X amount every month and consistently increase the savings amount by a percentage or several until it hurts. Pause for a month or two and then keep going. You’ll be amazed how much you can save. You just won’t know because you’ve likely never tested savings limits to the max.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
