The figures are very optimistic! Even though I technically could “retire” with only $200K saved up, I’m going to continue working until 2015 and should have quite a bit more than that, when all’s said and done. I just wanted to compute the minimum amount it would take to cover my essential expenses to see how little I would actually need to survive. You’re definitely right that it’s a great feeling seeing how attainable FI really is!

We also keep our Safety Nets in our Betterment accounts. We do this for two reasons: 1) the money is liquid, which means we have instant access to our Safety Net if we need it, and 2) when the money is sitting in a separate account, it is less tempting to access than if it’s in our bank accounts (plus it earns a better interest rate in a safe, conservative way).

There are three main categories of income: active income, passive income and portfolio income. Passive income has been a relatively loosely used term in recent years. Colloquially, it’s been used to define money being earned regularly with little or no effort on the part of the person receiving it. Popular types of passive income include real estate, peer-to-peer (P2P) lending and dividend stocks. Proponents of earning passive income tend to be boosters of a work-from-home and be-your-own-boss professional lifestyle. The type of earnings people usually associate with this are gains on stocks, interest, retirement pay, lottery winnings, online work and capital gains. 

Merchants receiving a large percentage of their revenue from the affiliate channel can become reliant on their affiliate partners. This can lead to affiliate marketers leveraging their important status to receive higher commissions and better deals with their advertisers. Whether it’s CPA, CPL, or CPC commission structures, there are a lot of high paying affiliate programs and affiliate marketers are in the driver’s seat.

When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing. 
Did not realize that there is a huge community exist for FI online. A bit embarass at myself for still working when I have almost 1M USD and my living expense (excluding travel) is 1K per month. I spend maybe 8K a year on travel for mileage running, flying parents in business class etc from the miles game hobby. This blog gives me serious encouragement to quit in a few years… When I do quit, I will move back come to cut my living expense further (single), and I take my parents to travel using the miles and points I earn. (took them to Arctic last month, and cross country road trip in Australia.)
