Calculating the motion of one body such as a falling rock is easy. It is something you learn in grade seven science.
Calculating the motion of two bodies moving around each other in space is more complicated, it is something you learn in high school physics.
Calculating the motion of three bodies is very complicated, something you would need a specific University education for. See the wiki site for Three-body problem – Wikipedia
What we can learn from this is that life is complicated. This is why there is no secret answer, no magic bullet.
If you are going to pursue something of value, there will be work. You need to constantly define and redefine what you are creating. You only need to uncover a small piece of the puzzle in order to have value for others.
