Anytime you interact with someone in order to influence them, you are attempting leadership. All of us have a predominant leadership style we prefer using. Problems arise when we expect others to adjust to that style. We may get what we want in the short run but alienate others over the long term. A better approach is to be flexible enough to attract the support and cooperation of others.
Ability consists of experience, training, and understanding priorities.
The only true test of ability is proven performance, not potential. Willingness consists of desire, confidence, and incentive.

Four distinct readiness levels, based on different combinations of task-specific ability and willingness, are possible.
