How do I know it work? This might be survivorship bias but whatever, I believe it worked for me. After practicing this for around a year, I developed a custom 3D visualization for our 3D scanner[3] which greatly improved the UX. Our customers loved it. We even filed a patent for it (pending though)[4]
For me, that little puzzle is usually a leetcode[5] problem, or to solve a non-trivial rubik (my humble collection here[6]).
