The one thing I learned though from all those childhood experiences though is that you never can depend on one source of income. Eventually my mom caught on and stopped giving me all those extra bags of chips and I had to figure out a new way to make money. No matter how safe something seems there’s always the chance that you could lose that income and be stuck with nothing.
Peer-to-Peer Lending: Earn up to 10% in returns by lending individuals, organizations and small companies who don't qualify for traditional financing through peer-to-peer lending platforms like Lending Club. You can lend $100,$1,000, or more to borrowers who meet lending platform financial standards. Like a bank, you'll earn interest on the loan - often at higher returns than banks usually get.

Now I’ve been using Swagbucks for a while and have found the money works out to just under $2 an hour so this isn’t something that’s going to make you rich. You’d have to work 2,500 hours to make$5,000 so that’s about three and a half months, non-stop. The thing with Swagbucks though is you can do it when you’re doing something else so I flip through surveys and other stuff while I’m cooking dinner or flipping channels.
Dividend Income: Dividend income is wonderful because it is completely passive and is taxed at only 15% if you are in the 25%, 28%, 33%, and 35% income tax bracket. If you are in the 39.6% income tax bracket you will pay a 20% tax on your dividends. My dividend income portfolio mainly consist of dividend equity and bond ETFs such as DVY, VYM, MUB, TLT, and IEF. Total stock and bond income is a little over $100,000 a year due to a heavy accumulation of stocks and municipal bonds after selling my house. The most liquid of the private investments are investing in equity or credit hedge funds, real estate funds, and private company funds. There will usually be 6 month – 3 year lockup periods. The least liquid of the private investments are when you invest directly into private companies yourself. You might not be able to get your money out for 5-10 years, depending on the success of the company and upcoming liquidity events. CD Interest Income: I only have one CD account left in the amount of$185,000 paying 3%. It expires at the end of 2018 and I’ll have to figure out what to do with it. After selling my SF rental house in mid-2017 for 30X annual rent, I’m left with about $500,000 in cash after investing ~$2,200,000. The best CD today is the CIT Bank 12-month CD at 2.5%. That’s pretty darn good because just a couple years ago, such a CD was less than 0.5%. The yield curve is flattening, meaning folks should take advantage of shorter duration CDs.
None legally required, but 7-21 days is standard for most employers. Typically, 10 working days. Many U.S. companies give only one week, and then frequently only after completion of a year of employment [e]. A recent United Nations survey indicates the average number of vacation days actually taken to be of 13 per year [f]. This corresponds to the fewest vacation days amongst advanced economies.
I like the way you have listed the ways to earn extra income and was quite surprise that you did not make mention of network marketing, which is a way to make extra income without quitting your regular, though most people view mlm as a pyramid scheme but the real pyramid scheme is a regular 9 to 5, because you can only have one president of a company at any given time and network marketing business model to promote product that can be used is really cheap to join and can offer a substantial extra income or what do you think?

##### So, it’s like the 7 Deadly (S)Incomes? Ha. Bad joke. I never really thought to count them up or even name them but I’m a big fan of having multiple streams of income. Let me count. 1) Earned income (freelance pharmaceutical copywriter) 2) Royalty income (published book) 3) Interest income (savings accounts) 4) Business income (my personal finance blog) 5) Pension beneficiary (RIP daddy) Crap. Only five and only 1 that pays anything substantial. Hmmmm. Time to brainstorm. Thanks, Doc.

4) Treat Passive Income Like A Game. The only real way to begin your multiple passive income journey is when you are making active income. The initial funding has to come from somewhere. Hence, treat passive income as a game that has various levels. If you fail to achieve one level, it’s not the end of the world since you still have active income and can restart. Furthermore, a game is meant to be played with integrity. Using shortcuts (non passive income streams), someone else’s income as a supplement (spouse), or one-offs (capital gains) does not count. The primary purpose of any game is to bring enjoyment to the player and beat the boss.
Leonardo da Vinci is another example of someone who was a "wide achiever," in the words of Roman Krznaric, author of "How to Find Fulfilling Work." Da Vinci was alternately a portraitist, an inventor, and a scientist. Krznaric says that in light of decreasing job security today, spreading yourself among several different jobs, as da Vinci did, is probably a smart thing to do.
This equation implies two things. First buying one more unit of good x implies buying {\displaystyle {\frac {P_{x}}{P_{y}}}} less units of good y. So, {\displaystyle {\frac {P_{x}}{P_{y}}}} is the relative price of a unit of x as to the number of units given up in y. Second, if the price of x falls for a fixed {\displaystyle Y} , then its relative price falls. The usual hypothesis is that the quantity demanded of x would increase at the lower price, the law of demand. The generalization to more than two goods consists of modelling y as a composite good.
I guess I just don’t understand why the specific importance of focusing on “dividends” instead of focusing on the total return of your investment, including stock appreciation. I don’t really care if a company decides to issue a dividend or not; presumably, if they don’t issue a dividend, then they’re doing other things to increase the value of the company, which will be reflected in the stock price of the company. As an investor, I can make money by selling a percentage of my holdings or collecting dividends, and I don’t really care how that’s divided up – it’s an artificial distinction.
Unfortunately, it took a while for the real lessons to sink in. I was probably 20 or 21 when I read Rich Dad, Poor Dad the first time, which means I wasn’t exactly sure who I was yet. I knew I wanted to work hard and make money, but I wasn’t sure how. This made me a prime candidate for  multi-level marketing pitches, and the dream of “getting rich quick.”

For instance, a business owner who works in the company she or he founded would have to pay an extra 15.3 percent in self-employment payroll taxes compared to someone who merely had a passive interest in the same limited liability company who would pay only income taxes. In other words, the same income earned actively would be taxed at a higher rate than if it were earned passively.
There are dozens of ways to generate passive income. However, the option you select has to do with two metrics: time and money. Either you have a lot of time or a lot of money. Most people usually don't have both. But, if you have a lot of money, generating passive income almost instantly is easy. You can buy up some real estate and begin enjoying rental income. Or, you can invest in a dividend fund or some other investment vehicle that will begin generating a steady income for you.

Blogging – I guess you could say I’m a professional personal finance blogger since I own two sites and I’m making decent money every month. The income started off slow but has been consistently increasing. It’s not as much as I make with my day job but my best blogging month was equal to about one paycheck at my old day job.  While I had to learn how to set up and use WordPress myself, you can learn how to blog and make money online at StartABlog123.com.
