You must use a blend of tactics to be the best leader that you can be. There is a balance of encouraging others and of critiquing them. You must give them the freedom to make reversible mistakes on their own, not micromanaging their every decision, but at the same time, step in before a situation gets out of control. If you are frustrated with them, you must find the balance of letting them know what is frustrating you, but doing so in a way that doesn’t paralyze them or make them fearful of making the wrong decision.
As a leader/teacher, you should be respected, not feared. The only fear that others should have of you is the fear of letting you down. To build respect, you must treat others right, say the right things, and do the right things. This also means that you need to have the courage to be disliked. You have to have uncomfortable conversations, calling others out when you feel that they are slacking or not performing their best work.
Always criticize in private, but praise in public.
Never gossip or talk about someone behind their back.
You should be willing to be brutally honest with others, if necessary, but pick and choose when to lay it all out on the table. If you constantly are tearing someone down, criticizing each mistake, but not reviewing the things that they are doing well, you can ruin a person’s confidence or build resentment.
