Good leadership requires two factors. Each person in the relationship controls one factor, and progress will only be made if both variables are satisfied.

They have to want something

The person you are leading has to want what you are leading them towards. It has to be a desire that came from them, not you. It cannot be manufactured, required, or enforced externally. They must have a keen, pulsating desire.

You have to provide value for them towards that thing

If they want something badly but you can’t help them make progress towards getting it in some capacity, they will drop you and move to somebody who can. This doesn’t need to be specific knowledge about the thing they are working towards. You can help them improve psychology or habits, or you can help them remove obstacles that are in their way, or do anything else that will help them achieve their end.
