Do you have a special “thing” with your team members? Is there something that you do only with them, either individually or together?
If not, then you should.
As a team
There should be something special that you do as a team that no other team in your organization does.
Here are some real-life examples that I have either initiated as a leader or been a part of:
First Monday Donuts.
On the first Monday of every month, one of us was responsible for bringing in donuts. In retrospect, this explains why our performance on the first Monday of every month was abysmal, but it was worth it.
