PCA National Advisory Board Member Dacher Keltner is a Psychology Professor and the Director of the Greater Good Science Center (@GreaterGoodSC) at UC-Berkeley. Keltner is most famous in the sports world for his study on NBA teams, when he identified a link between positive, supportive ‘touching’ (such as high-fives) and success on the court. Keltner is also a published author, most recently publishing The Power Paradox.

To Keltner, when players practice verbally communicate gratitude, by saying thank you for things that matter to them, it can go further than they realize. When players explicitly and directly thank others for the work they've done, they feel more connected. In this video, Keltner reminds coaches, parents, and athletes the power of saying thank you. When coaches thank players, when parents thank coaches, when players thank coaches and parents, and when players thank one another, cooperation and teamwork improves.

In many ways, saying thank you is a very underrated form of filling the emotional tanks of those around you.
