Thank you for sharing this my friend and permit me to say it is outrageous with the values of money called for some of them, it is actually easier said than done. As for me, I will engage in other things than this, I tried all of them when I was broke years ago but they are not easy as said, and if they are easy, a lot of people doing it successfully by now and must have been millionaires or be in their hundreds of thousand by now, but that is not the reality now, which means that something is fishy.
What I can say now is that the best which I know that is more honourable and that could deliver good success to anyone who tries it is digital marketing, though the value you called is outrageous as it might be so little for some people while it might be in multiple profits for other people, so it depends. What I see here is that luck, experience and preparedness matter, and I must say that I had tasted from the digital market money before to the point that I earned about $500 a week, but with time, it stopped against my plan, so there is risk and uncertainty involved as well.
However, those who can continue to engage with it, and also try to vary their targets and audience and learn more about SEO and how they can utilize ICT for their advantage might make the money in on multiple. But it is not all that is good and will be good and successful in that aspect, which makes it challenging on its own. But affiliate marketing is a very good way to go by in this aspect, if you can be commited to it, it is easy money if you find the right niche and tutors to put you through.
