My conclusion on such articles, books, movies and etc is simple - that is just past. Read it, watch it, evaluate other peoples experience, but make own decisions, live your own life. What they have done 20-50 years ago to become successful and rich now, does not work now. We are developing all the time. World is developing and changing every day. A story of "buy an apple for 1 dollar, sell it for 2 dollars, buy two apples and re-sell them, continues doing" wont work now. Simply because we have a oversaturated market. Lets be honest, we have overabundance of everything. That is why better try to create something unique, then copy someone else. All these life lessons a like fairy tales for current generation.
For what reading/watching them when at the end up of the day you are still following your own routine? Unless if at the first place you are not committed to change anything but are only curious, that is why you read and watch those types of movies/books. What they have done in the past are actually more harder because they have limited resources or information that time but now, all of us are blessed to have what they lack of.
We can now access information easily and cheaply via the internet. The tools or gadgets now are cheap and we can use that as well to easily achieve the things that we wanted in life. It's okay to be unique. This is more proudful and you can also write your own movie/books once you become successful.
