Dependable people reduce friction everywhere they go.

Friction is what makes organisations slow: the chasing, the ambiguity, the work that has to be redone. A dependable person removes friction from every process they touch, and the effect spreads well beyond their own tasks because other people can stop compensating.

Look at where you currently create friction for others, in delays, unclear answers, or work that needs checking. Removing one of these does more for everyone than adding new output.
