Evergreen content, which is described as that SEO content which stays relevant for a long time after its initial publication, is a good way to generate income.

You can select any of the above fields based on your skill sets to create second income source. There is no dearth of opportunities, only thing matter is to identify the right one, which suits you.

Recession can push your career 5 years back but with proper planning you can minimize its impact and remember Bad Times also don’t last forever.

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.
