Want to turn a customer or client into a rabid fan who showers you with social media love and never thinks about leaving? Then celebrate their successes. When they pay off a loan, pass a class, get a degree, reach a weight goal, win a certification, land a big account or complete a project, make some noise. Send a card or a text (or both). Pick up the phone and call. Sing their praises online. The cost? Nearly zero. The impact? Immeasurable. Get your team to recognize a cause for celebration when they see it, and encourage them to seize those moments. Your customers will love you for it.
