Yes reading a lot would be helpful. you should read more and more but dont read everything you see.
True, read a lot of articles but that don't believe that all of it is true. I think most rich people got rich either because they got lucky or because they have a deep knowledge about something and made money because of it. I think most rich people are heavy readers, they spent/spend a lot of time reading things to enhance their knowledge and also so that they won't forget the things that know before. And also, by thinking about it, there's no dumb person that got rich by himself. There's some dumb rich people but I'm pretty sure they weren't the one who made all that money.
Usually, the rich got rich because they bet against the public, they have a different thinking and for sure all information that is written in the internet are not 100% proven to be effective as the real rich does not share their method to preserve it.
Not entirely true. Rich people tend to share their experience. In fact, they love to! Look at Ted Talk, most of the people there are already successful in life. If you go to YouTube, there are people sharing how they got rich and all the lessons that they have learned throughout life.
I think if someone doesn't want to share his method or even his story, then he's doing something that cannot be shared to other people. Something fishy and maybe illegal.
Does it bother you that some info from the Internet aren't real? You can do one thing, stop reading the article. However, it will come to a time when you can easily identify if something is real or not.
