This is Simon, thank you for your post, it is very helpful for me. However, we are a lighting company, and we are plan to try the Affiliate Website to increase our sale. But it seem that there are many different Affiliate website to be chose and some of them also need pay some fee to begin, so as we just begin to do this, which website is your recommend ?

When I was working towards financial independence I calculated that every $100 I was saving I was buying at least 3 days of freedom in the future. This made saving easy. Most things weren’t worth 3 days of freedom!! I’ve designed this calculator so anytime you want to buy something you can determine whether it’s worth trading your time and freedom!
True, the world is a bit unpredictable. That said, if you’re invested in a very broad index (like VTI, VTSMX/VTSAX), you are as protected as possible. If those indexes collapse/devalue, there are far greater issues going on than money. You would be fighting to eat and survive at that point, and money would be worthless. So, other than the world ending as we know it, you can be FI and have 99.9% assurance you are financially safe.
Another one of the highest paying and most popular dating affiliate programs is eHarmony, which is based on the actual earnings that can be made from each referred sale. Up to $188 can be made from a single sale. In general, the members at eHarmony are typically looking to find serious long term relationships, so many of them are willing to pay extra to find similar people. 

As long as the network is legitimate, it can be a good way to pick up some extra money on a steady basis. You won’t make a fortune, since your rewards will be limited to how much money you will spend. You certainly don’t want to get carried away, spending money just to generate rewards. That could put you into a situation where you will spend more money than you will earn from the network.

I guess I’m in the Blockbuster Category, but living in the Midwest I’d have a hard time figuring out how to spend $300k/year even though the math says it is not a problem. I think the reality is most people who are super savers are going to get to Blockbuster eventually assuming they don’t inflate their lifestyle along the way. There is a lot of truth to more money not bringing you more happiness…I spend less in “retirement” than I did while working and I’m exponentially happier. I checked my taxable account for the first time this year and it in the first 11 days it is up more than I’ll spend this year, interesting times indeed.
