The doctor or lawyer, for instance, could use her or his income to invest in a medical start-up or buy shares of medical companies he understands such as Johnson & Johnson. Over time, the nature of compounding, dollar cost averaging, and reinvesting dividends can result in her or his portfolio generating substantial passive income. The downside is that it can take decades to achieve enough to truly improve your standard of living. However, it is still the surest path to wealth based on the historical performance of business ownership and stocks.
It’s funny you mention the different psychological levels of financial independence. I read a lot of blogs and there is this one Blogger who goes on every single other blog and shouts from the top of his lungs that he is a multimillionaire. But he has no self-confidence because his wife still works. His writing oozes insecurity probably due to the lack of friends, lack of success from his site, and lack of purpose. He also likes to write about his investments, but he’ll only publish his winners and never his losers and he’ll never talk about them when he does make an investment.

How do you gain financial freedom

Very useful and interesting ideas. To make a passive income is not an easy task as someone may say. It requires responsible approach and a lot of effort.I, personally, think of generating revenue from rental properties. And I was considering Queens in NY. However, I hadn’t even thought about trying index funds before your post, but now I believe it might be a good idea. Thus, thank you for sharing.
In the case of cost per mille/click, the publisher is not concerned about whether a visitor is a member of the audience that the advertiser tries to attract and is able to convert, because at this point the publisher has already earned his commission. This leaves the greater, and, in case of cost per mille, the full risk and loss (if the visitor cannot be converted) to the advertiser.
The organizing principle behind this grouping, appropriate economic units, is relatively simple: if the activities are located in the same geographic area; if the activities have similarities in the types of business; or if the activities are somehow interdependent, for instance, if they have the same customers, employees or use a single set of books for accounting. 

Partly as a result of different economic conditions of life, members of different social classes often have different value systems and view the world in different ways. As such, there exist different "conceptions of social reality, different aspirations and hopes and fears, different conceptions of the desirable."[33] The way the various social classes in society view wealth vary and these diverse characteristics are a fundamental dividing line among the classes. According to Richard H Ropers, the concentration of wealth in the United States is inequitably distributed.[34] In 1996, the United States federal government reported that the net worth of the top 1 percent of people in the United States was approximately equal to that of the bottom 90 percent. Cross-nationally, the United States has greater wealth inequality than other developed nations.[citation needed]
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
