Some days...

Some days you feel it.  And some days you don't.  

It's the power to turn your attitude around and make the decision to be unstoppable.

It means trying your best, despite the outcome.

You've done it before and you can do it now. See the positive possibilities. Redirect the substantial energy of your frustration and turn it into positive, effective, unstoppable determination.
