2 Things

Often, actions lead and emotions follow.  That's why when you smile at someone, it makes you feel happier than when you frown.

Grow your teams culture or be a better teammate by finding small but meaningful actions that will bring your team and teammates together and improved the emotional well-being of the team.

One systematic way to do that is called '2 good things.' 

All you have to do is say 2 positive or encouraging or motivating things per minute.  

Now, it's just like any new system - it won't run on it's own.  It needs to be clearly taught and communicated and modelled and there needs to be consistent re-teaching, follow through and feedback to make it a sustained part of your team's culture.  

But once it is, it the new level of communication and connectedness could be a game changer.
