Multiple streams of Income covers this strategy. I highly recomend you read it if for that reason alone. Beats the typcial buy and hold (or is that buy and hope), dollar cost averaging and other so called sensible stategies which don't work unless you have a 20-30 year time horizon. Ask anyone who saw their investments plumet during the Jimmy Carter years back in the 70's how long they had to wait to get their investments back up to break even level. Want to take a guess? Would you believe 15 years? That is close.
How do you do this?  Well, try to get the highest paying job you can!  Ask for a raise!  Utilize services, such as, to see how your salary competes with others in your same job.  Some companies really force employees to leave to get a raise, and then come back for another raise.   This industry jumping promotional strategy is very common and could work.
As can be seen from the above table, from the age of 45 onwards you are able to create a big source of additional income by just planning and investing Rs10,000 per month in equity SIP today. That is how simple it is to create a regular stream income by planning early. Of course, we do not know which stocks will give high dividend yields at that point in time so we have considered the quality high dividend stocks at this point in time. Above all, this approach is also tax efficient as you only have to pay 10% tax on dividends above Rs.1 million in a fiscal year.
The craziest part of this was I’d wake up in the morning and there would be more money in my bank account, from people who had bought my book overnight. When you think about it, an online store that sells something that’s digital is something that’s open 24 hours a day, 7 days a week, 365 days a year. Using tools, software and systems, you can automate the delivery process so you literally don’t have to do anything to serve that audience. That’s super powerful.
Most of us think of investment income as just the cash flow we get from bank interest, bonds, share dividends and property rents, some of which comes via a super pension.  But a more complete view is to also consider how growing the value of your investments can add to your spending potential.  This total return approach generates income from both income and growth to optimise spending from your portfolio across all market cycles, aligning cheap and expensive investments to your goals.
