It's a Japanese word, and it really means your sense of purpose.

If you go to Japan and you look at some of these cultures in Japan that are particularly long lived and ask them, why do you live so long?

Oftentimes they'll say, Icky guy, your reason for being?

Some people spend their entire lives looking for their icky guy.

Think about the things that you love, the things that you care about and also think about what the world needs.

One way to really try and find your icky guy is to say, Look, if money were no object, if I was no longer doing things in pursuit of any kind of material, things like money, what would I regret not having done with my life?

You can help with your sleep.

You could help lower some of the rates of chronic disease, and it can help you just feel better overall, more engaged with life.

You'll know it because you'll feel it.

It's that flow like state.
