Productivity boils down to high-velocity decision-making and a bias for action. This requires a) good intuition, which comes from experience, so as to make generally correct decisions given partial information, b) a keen awareness of when to move more carefully and wait for more information, because the cost of an incorrect decision would be greater than cost of the delay. The optimal velocity/quality decision-making tradeoff can vary greatly in different environments.
Self-direction — agency over your work and your circumstances — is the key to life satisfaction. Make sure you grant sufficient self-direction to the people around you, and make sure your career choices result in greater agency for yourself.
