Effective communication is key for leadership. Communication channels allow leaders to disseminate messages and should be used strategically. As the number of people increases, the number of communication channels needed to reach everyone exponentially grows, reinforcing the importance of clear, repeated communication that ensures messages are understood. Principles for clear communication include understanding the audience, engaging them, expressing ideas effectively, and getting confirmation messages were received. Setting clear expectations also requires understanding issues from different perspectives and giving context. Addressing an individual only focused on "what's in it for me" requires understanding their background, leading by example, and demonstrating their value and need as part of the team.
