I may be mistaken, but i was always under the impression that drinking tea is a long journey of learning
It might be for you. But then again, lots of things are a "long journey of learning". Riding a bike, cooking bread, watching action videos, building walls, tap-dancing, walking outside, reading books, cleaning the floor, growing chillis, cutting toe-nails. Always room for improvement.
And there are lots of things one can learn to do by feel rather than by measurement, but it doesn't mean the reasons for doing so are always compelling.
