Doubt is a block.
Children don’t question or hesitate about how to play; they simply do it. If there’s a block, it often comes from the adults around them or other external factors.
The same goes for cleaning. You only need to practice it. If you’re unsure about the method, you can even clean with that uncertainty. Through cleaning, you will receive the necessary information at the perfect time.
So, in this very moment, the only choice you need to make is whether or not to clean—nothing more.
