There is likely a bell curve of performance in any subset of investing or profession.
Choosing where to aim investing or working will affect the outcomes.
In the middle of the bell curve are the averages, average job, average methods, generally safe, able to lead the average American Dream.
Trying to work or invest at the ultra performance tail end of the curve requires a lot. Risk tolerance, hard work, better knowledge, better tools, better analysis, better methods, more education/tuition, EVERYTHING. THere is not a lot of room at the end of that curve, not many will get there.
Picture all the high school football players that want to be great on the pro highlight reel. Many lack the talent, work ethic, willingness to do what it takes. And for those that possess all the great tools, few will get there, some will suffer from injury. Some will progress to real greatness but this is rare. Some will flame out, or have brief success, they will turn to being mere bystanders, perhaps commentators, basking in past performance but not participating.
THe same is true for websites, there are few 5M annum sites, it is not easy. I doubt ET is in that realm. The same is true for great neurosurgeons or anything.
The safe path to riches is having a day job, living below your means, saving lots of money, adhering to boglehead type principles. Let compound interest work over time and you will get rich. In order to get more out of the market, more has to be risked.
I think many on ET think they want to be greatly enriched at the end of the tail. I don't see many with the talent, openmindedness, willingness, honesty, work ethic, etc... required to get there.
