Ask Larry Levine, author of Selling from the Heart, whether discipline is a negative word, and he’ll push back without hesitation.
“We choose to believe it’s a negative word because it requires something that’s difficult,” Levine said, “and that’s consistent work.”
Levine made the case that long-term success in sales isn’t built on big wins or chasing the next silver bullet—it’s built on small, repeatable actions done day after day. For cleaning industry professionals who live and work in demanding, fast-paced environments, the message is direct: your habits determine your results.
Levine has spent years applying what he calls the trust formula to the day-to-day work of professional service sellers. Whether you’re building authentic relationships, delivering meaningful value, or creating a memorable customer experience, he said, none of it holds without a foundation of disciplined habits.
He traces the lesson back to an unlikely source—his future mother-in-law, circa 1991. Before he proposed, she offered him a piece of advice he still carries: “If you can’t do the small things correctly, you’ll never be able to do the big things correctly.”
Levine said that advice is as relevant in 2026 as it was then. “If you can’t do the small things correctly with discipline, with consistency, with commitment, you’ll never be able to do these big things that we all like chasing as salespeople,” he said.
Levine offered three concrete habits that, if practiced every working day for 30 days, he said will produce measurable results.
