How effective are paid courses and should anyone rely on them?

Hello, so there are websites and then there are famous entrepreneurs who sell their courses to show how you can be a millionaire. They all are similar exclusive of the method they teach you. They all tell you to commit to your work, plan and don't miss out a day. There was a time many of us used to take tuitions from teachers at our school to pass the exam and there is this when pay for a course to learn how to make money. But is it worth it? Has anyone ever made it to being a millionaire or even make a living out of it? They giveaway free courses for reviews and more but what's the percentage of people buying a course and being successful at it?
According to me it's all crap and they just loot money of your wallets because hey, whose going to give out a million dollar secret? KFC would sell you a course on how to cook fried chicken but would they ever give out their secret recipe? Of course not, so everyone has their own ways of making money and you can't follow anyone because you have your own nature of doing things, your situation of how you are brought up in what surroundings and every little things matter on what you become, you may get to know a thing or two from these courses but you will never be able to do it. You should struggle and learn on your own to be one of them. All it takes is one brain and hardwork.

There is not secret recipe. Usually earning high amounts of cash isn't something secret, just a plain old blueprint. For example real estate doesn't really have any secrets, yeah sure someone might know a way or two to get better deals but the blueprint is the same. The "secret" stuff is usually bs, if you follow tai Lopez SMMA course sure you will earn a couple hundreds thousand if you get lucky and all that shit but I doubt you will become a millionaire from it.


Conclusion: yeah it's probably bullshit

Most information found in paid courses is almost always available somewhere else for free. Are you going to take the time to search for it? that's the question. The only value I see is that they typically have the information you need compiled nicely into an eBook or video platform. Aside from that, paid courses are mostly just "theoretical", and like everything else, will only work if you put in some effort and apply creative thinking.

I followed a self-professed money guru's email list to get a free e-book (not worth it btw, most e-books paid or not suck) and one of his emails sent me to a conversion page for his course (Can't roll my eyes anymore due to overuse on these fools) and he blatantly said he preys on entrepreneurs wanting to make money and capitalizes on them to sell courses and books to. Funny enough, the course he was offering was about how to sell courses. Not frauds, not good investments either.
