Yeah.

And I think the more research we do, the more we figure out how important it really is.

I remember my grandmother telling me, and I think this is something universal, that if you have to make an important decision, you have to sleep on it.

Literally, you know, don't make a decision tonight.

Go sleep and then tomorrow morning, you know, if it still feels good, then maybe you should do it.

And that's like a universal wisdom.

And I think maybe in the old days people thought it was useful because...

At least it made sure that you weren't hurrying yourself or you weren't putting too much pressure on yourself.

But now we realize more and more that now during our sleep, a lot of very useful things happen.

There are higher cognitive processes going on while we sleep and especially while we dream.

Yeah, it's one of the more famous and wonderful stories.

She was a writer already, but she hadn't written anything that, well, she hadn't written anything of note, let's put it that way.

And then she took the train from Manchester to London and

And in the train compartment, it basically just hit her.

The story goes that within about an hour or so, basically the entire Harry Potter story came to her with the most important persons, with the plot, the storyline, and she frantically wrote everything up.

Well, in the next 15 years, she had to work really hard to actually write all these seven novels.

But the idea came during a train ride.

And it was, again, one of those examples of an idea that is both beautiful and pure and more or less finished at the same time.

It came to her and it was all there.

Yeah.
