Wikipedia is great.
I take everything with a grain of salt, whether it be a wiki page or a well-respected book by a so-called “expert.”
I have learned so much from Wikipedia, that I don’t mind if a couple of the fine details are off. It’s opened up my mind to subject matters that I otherwise never would have touched.
For me, as a polymath / aspiring polymath, it’s all about breadth of knowledge, not depth. My “Cliff Notes knowledge” of a million subjects wins out over a specialist’s extreme details, any day.
Connecting the Dots
This is because my strength is not being super-detailed or specialized, but in being able to make out-of-this world connections between unrelated subjects. This ability allows me to walk into a room of experts and see solutions to problems that they never would have dreamed of. They still get to do the detail work that makes it actually function, but I produce the idea that enables them to get started (or the solution that allows them to get unstuck).
I’ve personally learned psychology, accounting, graphic design, advanced marketing, modern business methods, philosophy, basic pharmacology, and many other things from self-teaching myself online.
I have a double major in marketing and consumer science, as well as a minor in sociology from a legit college. I can honestly say that I’ve learned more about those subjects, too, from self-learning online.
College was a complete waste of time, not to mention that it screwed me over financially, due to student loans. I had to have that “piece of paper” that was supposed to land me jobs: I want to set fire to it.
Your Experience May Vary
Not to brag, but to be fair to readers of this post: I have an IQ of 170, and my personality type is an ENTP (“The Creative Inventor”). This means that not only am I technically a genius (in the 99.9998467663 percentile), but my personality type means I am primarily driven by curiosity. So, not everyone is built to be a generalist. Specialists are needed and serve an important function in society. However, there will continue to be a rise of generalists, due to technological evolution.
