What does 'Stay Hungry. Stay Foolish.' mean?

Hi,
What does ‘Stay Hungry. Stay Foolish.’ mean?

Hi.

I had never heard it before, but this sums it up.

Stay Hungry: don’t be too easily satisfied or grow too comfortable.
Stay Foolish: Brand and his folks liked to think of themselves as “fools” in an overly serious world
I googled them… But someone else can explain clearly?

Many thanks Mordant for posting this link. I got it.

Hi Mordant,

Thank you. I believe the explanation is definitely accurate.
