Initiative is an important attribute for a great teammate because it demonstrates a recognition of proactive thinking and self motivation. Ordinary teammates require a prompt of some kind to do their job. This prompt can come from a leader, circumstances, or both. Great teammates see potential problems and solve them before they become an issue. Taking initiative is risky because it means taking responsibility without having the excuse of someone or something making the decision for me. What type of teammate do you want to be? The one that solves problems no one knows about or the one that has to be told to clean up messes from problems that already happened?
