Show them, tell them, let them try, and give them praise, or they won't take action.

Engage in discussions, listen attentively, approve ideas, and delegate responsibilities, or they won't grow.
『話し合い、耳を傾け、承認し、任せてやらねば人は育たず。』
Watch and appreciate their efforts with gratitude, and place trust in them, or they won't cooperate.
『やっている姿を感謝で見守って信頼せねば人は実らず。』
と表現できます。
