Leadership vs. Management

Another stub.

"Manager" tends to mean that you have clear targets and metrics. It's the part of an operation that's subject to engineering considerations, because you can optimise things. Objectives are given.

"Leader" tends to be mean that you create emotional engagement (which in turn tends to mean that you need to at least 'not suck' as a manager). It's the part of the operation that's subject to humanistic considerations, because you (intentionally, or otherwise) are able to satisfy your co-workers' feelings. Objectives are created.
