PCB Design Feels Like Solving a Puzzle

The more I learn about PCB design, the more it feels like solving a giant puzzle.Every decision affects something else.Move one component, and routing becomes easier.Widen one trace, and another signal suddenly has less space.Add one via, and impedance changes slightly.I think that's what makes hardware engineering so satisfying.There's rarely a single "perfect" solution—just a series of smart compromises.That's probably one reason I enjoy learning it so much.
