With a huge challenge, money comes along (like with setting up my proxy) but when you are building hundreds of proxies to gain an extra dollar on each proxy, you are screwed.
When there is a challenge to make money I will definitely do it. Money always promote challenge no matter what IMO.
The challenge of making an ongoing income is that keeps me here. Each of my web sites are a pipeline of ongoing income.
Usually, till 100k a year, it's money and then challenge. But for me, challenge keeps me on drive. If something is challenging and bring's great satisfaction then it's bound to bring money later.
hmmm.. Well, long long ago, when we lived in the bubble(called the 90's) I was all down for the challenge. I wanted to write the coolest code, make the best design, or rank over everyone else with my own two hands. Now that Im much older, I rather have the idea, and pay someone else to do the work, that way I can pay myself just for ideas. Basic ROI IMO.
Although it does feel great when you create a site yourself that becomes successful, the money is still the most important.
I am motivated by the money, this is why I spend many hours online a day! I do have a few sites that are personal as well just for friends and family.
