“In a room of 100 strangers, seek similarities. In a room of 3 friends, seek differences.”
Popular wisdom warns against creating a bubble of similar friends. You often hear that you should make a diverse group of friends. That you should seek to spend time with people with different world views. This advice is overrated and over esteemed.
Instead, when deciding who you work and spend time with you should focus on similarities. But once you've found those people, you should emphasize differences.
On every successful team, there is internal conflict. From the outside looking in everyone seems similar. They have a similar mission, similar values, and a similar perspective on life.
But within the group, the approach they take to reach their common goal is hotly contested. There is beneficial conflict, differences of opinion, and a regular clash of ideas.
Successful teams work together because of the deep similarities in their ideal future, but they work well together by emphasizing the differences in how they want to get there.
