I was contemplating reality as a simulation when I had a eureka thought. The thought (or idea) is how the simulation creator and the simulated relate to each other. It came to me all in a flash, but I was able to describe the thought in full back to myself, without words. But when I went to verbalize it, to make audible the words in my head, I failed at it. My brain couldn’t slow down to the speed of my mouth without losing the clarity of the thought. Is the skill of rendering complex ideas into words teachable? How are philosophers able to recreate the words of the mind into the words of the mouth, or pen?
Philosophy is the art of translating those insights into words, and like every art it takes some time to develop your 'voice'. The only way to do that is to sit down and do it, step back and look at it with a critical eye, and then sit down and do it again. You have the tools — analysis, analogy and metaphor, logic, etc. — so sharpen them any way you can and put them to work.
I suggest you start by scribbling. When you have that kind of flash, sketch it out on paper any way that makes sense to you; make the idea concrete. Then start the critical thinking process, asking yourself how you will make this idea sensible to others. What logic do others need to see that might not be clear? What assumptions are you invoking that may not be self-evident? What language can you use that others will find accessible? Don't expect instant gratification, because it will take time and effort to piece it out.
Outside the realm of pure logic, math and science, trying to clarify and transfer some private qualitative experience or ideas into public correct words is always full of traps here and there, that's one of the main reasons why philosophers so far haven't successfully completed such a grand project of Alphabet of human thought.
For me a major practical issue to apply to real life situations is due to epistemic contextualism and relativism, especially when you're dealing with beliefs, cultures, justifications and religions. In real life situations, background context is much more complicated than pure scientific or logic realm since it's essentially a nearly infinite network with too many parameters. So to achieve your goal of transferring ideas to words correctly, you need to squarely focus on context clarification and simplification. Even after doing so, due to modern society's numerous kinds of relativism, your carefully transferred words will still get misunderstood inevitably by many holding different views than yours.
Some schools of thought completely reject language word as the unit of our innate ideas and thoughts at our fundamental cognitive level, under this view, your wish is impossible to be perfectly achieved even in theory...
