But gray is black and white.

So you have to look closely at the black and at the white before you can see the gray. Really look... refrain from just glancing...there is so much there. It's never a simple as it seems.

Same with the things that don't seem to be working. The answer is there, really. Not that they aren't working but why. Doing the same thing over and over when it's not working is the only way to take a good look at the 'not working' so you can see what's there.
