We can't have complex ideas
When learning new complex things, you must find out how to make the complex simple. I have no complex ideas. I have only been taught and learned how to break down complexity into a set of related simple ideas.
The obvious analogy here is Computer Science. Many people think they could never learn how to code and that it just doesn't mesh with their brain. But when you start to understand CS, you necessarily start to understand its simplicity. You are not mastering the complex, but mastering breaking down the complex into the simple. When you solve a coding problem, you do so by organizing a problem in such a way that each sub-problem is easily solvable, because (most of us) aren't actually smart enough to figure out the big and scary problem.
The "complex" things I understand are a bunch of simple ideas, just with a specific set of useful connections. In a language you have all these tiny simple pieces of grammars and vocabulary, and by mastering these simple aspects, you can put them together it ways that seem complex.
Can any big idea you have not be summed up in just 3 or 4 simple premises (even if those premises are truly made up of smaller ideas)?
This could be why Occam's Razor so often applies?
All complicated ideas are just a connected set of simple ideas. Master the basics.
