When you're a leader, you're the one in charge of your company's mission and vision. But you can't realize that vision alone.

The vision itself, however, must stem from the leadership team. A vision starts as a big, grand thing. You have an idea of where you want to go.

Great cultures are built one decision at a time. 2. Purpose. Make sure members of your team know why they exist. Connect their jobs to the big picture and communicate the impact of their work.
