#1e2: Why should you scale your communication?
In some situations, you'll find yourself needing to not only communicate to people but through people. As a front-line manager, you can directly communicate a vision and strategy with your team. Yet it's likely that this strategic direction was communicated with you by someone higher up.
What works for you managing an eight person team won't work when you lead a company of five hundred. Here, it is important to have a clear and inspiring message that can be easily shared. (This is true even outside of people leadership — as a thought leader, you want others to reshare your message.) But you must also take ownership of growing the communication skills of others.
In communicating to others, you scale linearly; through others, you scale exponentially.
