The book is not bad but it's not that great either. Think of it as an idea book in which you see him mention something and then research it futher. The rambling just becomes too much as you move along to the point where it becomes annoying to read. The tone the author uses is very nonchalant and he doesn't really explain anything. Ideas are just thrown out.
So many great tips in this big post, thanks! I think it’s so true that people should focus on the things they do well at and are interested in. And yes save, save, save in the beginning and throughout. I have several interest and dividend earning investments and am looking to expand further. Diversification is a great goal for all of us so we can avoid having all our eggs in one basket.
Stocks (shares) paying dividends are typically a reliable source of income but they have higher risk of capital losses than cash and bonds. So, it’s wise not to chase yield indiscriminately.  The 10 highest yielding stocks on the ASX 200 (the 200 largest companies in Australia) are shown in the table below.  But their share price performance on average over the last year has been underwhelming, as shown in the far right column:
That is a nice list of passive income sources. Actually, the most up-to-date list of dividend growth stocks is the list of dividend champions, maintained by Dave Fish. The list of dividend aristocrats is incomplete at best. For example, the dividend champions list has over 100 companies that have managed to increase dividends each year for at least 25 years in a row. The list of dividend aristocrats has no more than 50 – 60.
If you have a knack for teaching and if you are an expert in some subject, you can become a tutor online for students. There are tons of websites like TutorVista or where you can try out this. You would need a great internet connectivity for this. It can work best for someone who is ready to work late in nights as many students from US and Canada would be right fit for you then.
While it is important to find something that you love to do and turn it into a money making business, you do have to be cognizant of the return as you pointed out. There are many opportunities that I found and tried out that at the time seemed great. But when I took a step back, I realized that I was working a lot for very little income whereas other things I love doing brought in much more money.
India's current account deficit reached an all-time high in 2013.[298] India has historically funded its current account deficit through borrowings by companies in the overseas markets or remittances by non-resident Indians and portfolio inflows. From April 2016 to January 2017, RBI data showed that, for the first time since 1991, India was funding its deficit through foreign direct investment inflows. The Economic Times noted that the development was "a sign of rising confidence among long-term investors in Prime Minister Narendra Modi's ability to strengthen the country's economic foundation for sustained growth".[299]

I remember seeing a number of my co-workers get laid off in 2008 and many of them had only worked for the one company. They had mortgages to pay, colleges to pay and families to support and they were scared out of their minds for what they would do next. After watching that happen, I vowed that I wouldn’t suffer the same fate. It’s one of the main reasons I started my own company. I tell people now that instead of one boss (i.e. one company), I have hundreds of bosses and it makes me feel more secure about my longterm prospects.

1) Save Like Nobody Owes You Anything. Passive income starts with savings. Without a healthy amount of savings, nothing works. Your overall “Money Strength” will be an F- if you do not build a financial nut. In our current low interest rate environment, you must save even more than before. It’s important to also realize that the savings I am referring to is AFTER-tax savings. You need to save money after contributing to your 401k and IRAs since you can’t touch pre-tax retirement accounts without a penalty until 59.5. Ideally everyone should max out their pre-tax retirement funds first, but if you don’t have enough funds and want to retire earlier then a decision to have more accessible post tax money will still work.
My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.
I first discovered the power of passive income when I was a senior in high school. I started a mobile billboard business where I would rent a small piece of land from someone who had land along a busy highway. Then I would place one of my billboard trailers on the land and rent out the ad space on the billboard. I would usually charge about $300 per month for the ad space, meanwhile I was only paying $50 per month to the landowner for the ground rent. I got to the point to where I had 9 billboard faces and was making quite a substantial income for someone in high school. I really learned how passive income could free up my life… this business is what lead me into investing in real estate.

The average population of counties with per capita incomes above the state's was twice as high (921,098) as those with a per capita income below the state average (546,543). Even this difference is minuscule when population density is considered: Counties with a per capita income above that of the state were eight times as dense on average (1,540.2 persons per square mile) than those with per capita income below that of the state (192.1 persons per square mile).
There are a ton of ways to diversify your investments, some of which can send real income your way. By opening a brokerage account and investing in ETFs or mutual funds, you can earn real returns you can use to supplement your income. Of course, the flip side can also happen – as in, you can lose money. So, make sure you understand the risks before you dive in.
