It's the third brightest thing in the sky after the sun and the moon.

Next brightest thing is the International Space Station.

And you can just watch it go over your head from horizon to horizon.

An unmistakable little beacon of...

how we behave when we do things right.

And we need examples like that because we're always going to be messing the other stuff up.

That's a big question.

It's a very personal question because life means different things to different people.

And I think it also means, you know, I have a seven month old granddaughter, her answer to the meaning of life would be different than my 10 year old granddaughter or my 40 year old daughter or, or my wife and I at different stages of your life.

There are different goals and purposes.

I think my generic answer though is, um,

Have dreams.

Have things that are important to you.

They don't have to matter to anybody else.

But maybe a little internal thought experiment.

If my life goes perfectly from here forward, what will happen?

And if you don't have an answer to that question, then the odds of your dreams coming true are greatly diminished.

But if you've gone through the little self-thought experiment, what is it that I actually dream of?

I remember when I was 10, but now I'm a busy adult and I don't dream of anything anymore.

I think that's a self-destructive way to live.
