In athletic training, enthusiasm cannot substitute for biomechanical correctness. If your joint angles are misaligned, repetitions do not build muscle—they generate structural wear and tear.
This mirrors optical engineering precisely. You can invest millions in high-output LED chips, but if the primary TIR reflector angle drifts by half a milliradian, the light scatters into glare rather than reaching the architectural target.
True mastery across all domains is quiet, patient, and obsessed with foundational correctness.
