Tough? Maybe, but I"m going from very simple logic:
Every one of these chattering monkeys is in the same situation. If any of them actually had any skill, what would they be doing? They would be using their skill to make themselves rich. They would not be typing away on the internet desperately hoping to make a living from advertiser clicks, Amazon sales commissions, or selling training courses. And for sure they would not be publishing the recipe for the secret sauce so that everyone could use it. The surest thing in investing is that any publicly known trick that works will eventually be useless as the hoards try to take advantage of it.
What keeps things going is first that people want to believe in skill and luck. That's why the casinos and lotteries will never go out of business. But second, when something happens there are so many monkeys that one or a few of them will have predicted it. They will then be anointed genius monkeys and sit in that throne until their next few pronouncement turn out to be busts. Since there are always genius monkeys many people always have the hope of finding the genius monkey ahead of time. If they do, it is pure luck, but they will conclude from that luck that they, too, are geniuses.
