What is culture? What does it mean to develop a culture?
A definition for culture, and there are many, is: "people like us do things like this."
People like us, students of being better versions of ourselves to serve others, are open minded to new ideas. That's the culture of someone like us. But what if I was a team manager?
People like us, people on this team, celebrate micro-wins every day because we know that a war is won through many tiny victories. But what if I was thinking about my friends?
People like us, friends, earnestly make efforts to see each other and share our lives with one another. But if what if...?
Culture happens first at the micro-level, in small groups - pairs, cohorts, families, friends, neighborhoods. Then, it expands.
If you want to create a team culture, then you and your team get to answer this question: What are the things that people like us do? And who do we serve?
Once you have the answer, the next step is to decide to do it.
Once you have do it, and repeat it, and improve it, you will have created a culture.
