What's the one habit that changed your production more than any script?

Not a tactic, not a carrier, not a lead source. A habit.

For some people it's a fixed dial block that nobody is allowed to schedule over. For others it's the ten-minute end-of-day review: every contact logged, every follow-up dated, before the laptop closes. Some swear by calling their own book quarterly; some by never taking an application without the draft date verified on a bank statement.

What's yours, what did the numbers look like before, and what do they look like now?

Rules for this thread: one habit per reply, the number it moved, and how long it took to stick.
