Pushkin.

Positive psychology, the field that studies the science of happiness, has made a lot of progress in the last few decades.

So much so that we've only been able to scratch the surface on all the cool studies out there,

even in the hundreds of episodes I've hosted in the five years of the show.

We've spent time looking at the positive effects of treating yourself better and being kind to others,

but we haven't talked as much about the happiness boost we can get from getting out of our comfort zones

and taking on unfamiliar or even uncomfortable things.

Some people seem to love pushing these boundaries.

You know the type.

Someone who treks across an entire continent, sets up a wildlife sanctuary, patents some new invention,

and drops everything to become a novelist.

These people can seem larger than life,

but they do exist.

And one expert in well-being science

thinks we should pay more attention to them.

So thank you so much for having me.

I'm sorry, I'm just running around today.

Oh, no, this is like.

Yeah, I really enjoyed the new book.

Oh, thank you.
