I know this is repeating what others have said to some extent, but I think everyone's suggesting that you learn our current most optimal methods for finding low move count solutions. Once you have solid foundational knowledge of what current FMC experts have already discovered, you may even be able to begin working more on your own theory. It's like learning or inventing nearly anything.
For example, the majority of great scientists didn't invent groundbreaking theories overnight. You learn everything we already know, then apply your own creativity with the knowledge that other's have already uncovered through your own informed observations. Human knowledge is an intergenerational accumulation of information--all that we have is a constantly growing database of shared information. FMC is a very construction of the human mind--a challenge to solve a human-developed puzzle in as few moves as possible. Others are able to consistently get sub-20 or nearly sub-20 singles/means, so by learning how you can get to that point, you can begin developing new things for yourself. The resource of experts in an existing field (in this case, FMC) is invaluable. They started off with nothing as well, and becoming extremely good at FMC didn't occur overnight. I commend you for trying to think outside of the box, but without foundational knowledge of advanced methodology, you're running in circles. We are all human (yourself included), and by constructively taking the advice of accomplished FMC competitors, you're more bound for success and expanding your creative capabilities than already deeming yourself a future expert without foundational knowledge of the event.
