Who to learn from? Which Knowledge is valuable?

Due to the Huge* interest in my last blog about how knowledge/learning has given us all of our advantages in life.

let me continue :)

Ever since humans discovered agriculture, we have had enough food so that we can afford to be Lazy!

Meanwhile people hate feeling useless and pointless.

Therefore an enormously huge amount of fictitious (fictitious means "NOT Real" btw.) stories have been created in order for us humans to feel as if we are doing something meaning ful. For Example:

1. Religion
2. Alternative "Sciences"
3. Hocus bocus, fortune tellers :D
4. Even traditional science up to a few decades ago was so out of sync with reality

Basically 99.99% of knowledge accumulated prior to 1990 has already been replaced with much better theories that match reality much better!

And to be more clear I mean topics even such as:

1. Cooking
2. Health
3. Wealth
4. Selfdevelopment
5. Economic theory is constantly being updated.
6. Political theory
7. Marketing
8. Communication
9. Coding
10. Hardware
    ...........

Basically Everything!!

Everything has been updated!!

Therefore you need to learn from the best in their fields, that have the most up to date knowledge.

If you think you can learn from a person who has stopped learning himself 20 years ago.... :D
Go to the University or to your parents! :D
