Effort inside a method that cannot work is the most convincing way a person avoids changing the method.
Intensity is the easiest link on the chain to change, which is why it is the first one people reach for when nothing comes back. The belief that this altar answers sets the state, the state delivers urgency, urgency drives more volume and more motion, and half a day of it compounds into nothing but proof that more was tried.
Sincerity was never the variable. The silence was not a verdict on their commitment. A person can spend years at maximum effort inside a method that was never going to answer, and the cost is the years, while the belief that spent them comes through untouched.
