Execution requires choosing what deserves less attention.

Everything cannot receive full attention, and pretending otherwise means the important parts get the same care as the trivial ones. Execution is largely a series of decisions about what will be done adequately so that something else can be done well. Choosing what to neglect is a skill.

Before your next project, name what you are deliberately doing at seventy percent. Making the choice consciously is what protects the parts that actually determine the outcome.
