I can relate to some of what you’re describing. A lot of things that I know or solve just happen. I make absolutely no effort and it happens almost instantaneously. It’s extremely fast. However, if I can’t get it that way, I typically have to externalize the whole process, either by writing it down, talking to someone or myself, or acting it out. But, once I practice the information to the point that “feel it”, it turns into that super fast automatic process. People will often say that I’m smart. Even just this week, someone called me a genius. Really, I think I’m pretty dumb. I just have this ability to practice/engage in something long enough that it becomes automatic knowledge that I feel.
