Climate change is going to require collective action.

On a new episode of LifeKit, we're walking you through

what sort of climate-friendly choices can make an impact in your life

and the lives of others. Listen to LifeKit, part of NPR's Climate Week,

wherever you get your podcasts.

I'm Dacker Keltner. Welcome to the 100th episode of The Science of Happiness.

Nearly four years ago, we launched this podcast to explore the many paths to happiness,

featuring the research that we cover here at UC Berkeley's Greater Good Science Center,

where we produce the show.

When I think back over these four years, I'm filled with so much gratitude

for the stellar production team, for all the incredible guests,

and to all of you, our listeners, for joining us on this journey.

Thank you for all of your emails of support

and for sharing your own inspiring stories and reflections with us.

On each episode, we ask our guests to try a research-tested practice

to help them bring more joy or connection or goodness into their life.

Each day for the past week, I wrote down three things that went well for me

and I explained why they happened.

More after this break.
