Reliable isn’t a trait you’re born with. It’s a stack of Tuesdays where you did what you said.

Dependability is not a personality setting, it is an accumulation. Nobody is naturally the person others count on; that reputation is assembled from a long series of unremarkable occasions where the thing said and the thing done matched. Each instance is forgettable and the sum is not.

Pick one recurring commitment and keep it exactly for a month. Choose something small enough that you will not be tempted to renegotiate, and let the stack build without commentary.
