The best managers make giving responsive, constant feedback a habit. It takes time and energy to stop what you are doing regularly, tune in to each person’s performance, think carefully, say something to evaluate each person’s work so far, and then keep each person moving in the right direction. But it will transform your relationship with every person you manage.
Their work becomes art because you remind them to be purposeful about every single detail. They build their repertoires of ability, one day at a time. From focusing, they learn focus itself and become black belts at whatever they do.
