WHAT CAN’T GO ON GOES ON, TILL IT DOESN’T: “Courage to change what must be altered”.

And here is the quote from Churchill Peter uses.  This one goes out to all the doomers out there. Tattoo it on your forehead for ease of remembering:

Success is not final, failure is not fatal: it is the courage to continue that counts.

Courage is rightly considered the foremost of the virtues, for upon it all others depend.
