How do I clean faster and to a higher standard?

You can get things clean, but doing it quickly and to a real standard feels out of reach. That gap is normal. Speed and quality do not come from rushing or trying harder. They come from method, the same steps in the same order every time until your hands know them without thinking. Watch how a skilled person works and you will see they waste no motion. Top to bottom, dry before wet, one direction, no going back over the same spot. The standard is not about scrubbing harder. It is about doing the right step once instead of the wrong step three times. Pick one task you do often and learn the proper order for it, then repeat it that way until it feels natural. Master one before adding another. Efficiency is just good habits stacked up. You are closer than it feels.
