This is the Guardian.

Last week, New Zealand's Prime Minister, Jucinda Arderne, announced she was resigning.

I will not be seeking re-election.

My term as Prime Minister will conclude no later than the 7th of February.

It took the world by surprise, particularly those who have admired her political tenure.

This has been the most fulfilling five and a half years of my life.

I am leaving because with such a privileged role comes responsibility.

The responsibility to know when you are the right person to lead and also when you are not.

And although she didn't say it explicitly, many have interpreted what she described as feeling burnt out.

I know what this job takes and I know that I no longer have enough in the tank to do it justice. It's that simple.

Being Prime Minister during a terror attack, COVID-19, the climate crisis,

is undoubtedly going to take a toll.

But her speech also seemed to strike a chord with lots of people who are feeling similarly exhausted by the past few years. So today we're asking what is

burnout and what are the best ways to recover if like Jinda, you just don't have anything left in the tank.

Laurie Santos, you're a cognitive scientist, your professor of psychology at Yale University and your

creator of the university's most popular course ever called Psychology and the Good Life

and on top of all of that you present the Happiness Lab podcast.

First of all, tell me what it's like to be a happiness guru.

Does that label come with a certain amount of pressure in of itself?

Yeah, I mean, unfortunately it does. I mean, I think people really do expect you to practice what you preach,

right, you know, so you can't be up there telling people all these things they should be doing
