Leadership involves communicating goals to motivate and guide others to timely achieve organizational objectives. Effective leaders provide direction and meaning, generate trust, embrace risk-taking, and communicate hope using their communication skills. There are four leadership styles - Type A focuses on facts and logic, Type B prefers creativity, Type C makes emotional decisions ignoring facts, and Type D wants power and control through strict organization. The most effective leaders can apply all four styles appropriately based on each situation's unique people, tasks, and environment.
