Productive people eventually learn that subtraction is a serious skill.

Removing things is a genuine skill and it develops late. Anyone can add commitments, tools, and projects; deciding what to cut requires judgment about what matters, willingness to disappoint someone, and tolerance for being wrong in a visible way. It is the harder half of getting anything done.

Practise it deliberately. Once a month, remove one commitment, one tool, and one recurring obligation. Treat it as maintenance rather than as an admission of overreach.
