Robert McNair

I love the story of Robert McNair. He was kicked out of a library when he was 9 years old because he was black. He went on to get a PhD in Physics from MIT and then became an astronaut.  Now the library is named after him. 

The old adages apply:

It's not over until it's over

Hope springs eternal

The truth is the truth is the truth. And as long as you tell the truth, you'll be okay in the end.

and good old:

It's not over until the fat lady sings.
